๐Ÿšจ CVE-2026-65976
Deskflow is a keyboard and mouse sharing app. From 1.17.0 until continuous build 1.26.0.300, a connected peer can send repeated DCLP DataChunk messages to ClipboardChunk::assemble() in src/lib/deskflow/ClipboardChunk.cpp, causing the server path in src/lib/server/ClientProxy1_6.cpp or client path in src/lib/client/ServerProxy.cpp to append data beyond the DataStart declared size and configured clipboard limit before DataEnd validation, exhausting receiver memory. This issue is fixed in continuous build 1.26.0.300.

๐Ÿšจ CVE-2026-47719
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Prior to 1.3.2, the DEVICE_WEBAPI_REQUEST and DEVICE_PROPERTY Socket.IO handlers in server/runtime/index.js omit isSocketWriteAuthorized and accept attacker-controlled property.address or endpoint connection data. A remote unauthenticated attacker can make server/runtime/devices/httprequest/index.js call axios.get against arbitrary HTTP or HTTPS destinations, connect to reachable OPC UA or ODBC services, and receive results through the corresponding Socket.IO event. This read SSRF oracle can expose cloud instance metadata, internal administrative services, industrial endpoints, and ODBC data reachable from the FUXA host, including when secureEnabled is true. This issue is fixed in version 1.3.2.

๐Ÿšจ CVE-2026-47720
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Prior to 1.3.2, the TDengine DAQ storage connector's escapeTdString function in server/runtime/storage/tdengine/index.js doubles single quotes but does not escape backslashes. A remote unauthenticated attacker can submit a crafted sids tag identifier through GET /api/daq or the Socket.IO DAQ_QUERY event so TDengine interprets the backslash and quote sequence as SQL syntax. The injected query can return every row from fuxa.meters, exposing historical PLC tag values, device identifiers, and device names even when FUXA authentication is enabled. This issue is fixed in version 1.3.2.

๐Ÿšจ CVE-2026-47721
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Prior to 1.3.2, POST /api/scheduler and DELETE /api/scheduler in server/api/scheduler/index.js do not consistently enforce authJwt.haveAdminPermission for scheduler settings. An authenticated non-admin operator can create or alter deviceActions that invoke onSetValue or onRunScript, or delete schedules, gaining access to device-value changes and server-side project script execution normally reserved for administrators. Scheduled and repeating actions can continue changing PLC setpoints, safety interlocks, device state, or project data after the operator's session ends. This issue is fixed in version 1.3.2.

๐Ÿšจ CVE-2026-52731
ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, an attacker authenticated to an enabled Zebra RPC endpoint can terminate zebrad by supplying a getblocktemplate LongPollId containing multi-byte UTF-8 characters. In zebra-rpc/src/methods/types/long_poll.rs, LongPollId::from_str originally checked the input byte length and then sliced fixed byte ranges to parse encoded fields. A slice boundary can land inside a multi-byte character and trigger Rust's byte index is not a char boundary panic. Zebra release builds use panic equals abort, so one malformed authenticated RPC request terminates the entire node process and can be repeated after restart. This issue is fixed in version 4.5.0.

๐Ÿšจ CVE-2026-52732
ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, one unauthenticated P2P peer can monopolize all 25 MAX_INBOUND_CONCURRENCY slots in Zebra's inbound mempool download and verification pipeline. In zebrad/src/components/mempool/downloads.rs, the bounded queue was shared globally without per-peer accounting, while peer identity was not carried through Gossip and FullQueue responses were mapped to Response::Nil instead of reaching overload disconnection handling. An attacker can advertise fake transaction identifiers and remain silent so each task holds a slot until TRANSACTION_DOWNLOAD_TIMEOUT, then periodically refill the queue as slots expire. While saturated, honest peer transactions and local sendrawtransaction requests are rejected with MempoolError::FullQueue, although block validation and synchronization continue. This issue is fixed in version 4.5.0.

๐Ÿšจ CVE-2026-52733
ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, a natural or attacker-influenced chain fork can leave stale Sapling and Orchard note-commitment subtree roots in Zebra state. In zebra-state/src/service/non_finalized_state/chain.rs, Chain::pop_tip removed a reverted tip block but did not remove subtree entries whose end_height belonged to that block, unlike the cleanup performed by pop_root. When the winning fork later finalized, the abandoned branch's stale subtree data could be written to RocksDB and survive node restarts. The corrupted history can cause z_getsubtreesbyindex consumers such as lightwalletd and light wallets to receive incorrect subtree roots, producing wallet synchronization failures or incorrect wallet state and requiring a full state rebuild for recovery. This issue is fixed in version 4.5.0.

๐Ÿšจ CVE-2026-52734
ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, an unauthenticated P2P peer can cause the mempool download pipeline to retain transactions after verification reaches the outer RATE_LIMIT_DELAY timeout. In zebrad/src/components/mempool/downloads.rs, Downloads::poll_next removed cancel_handles entries after success and ordinary verification errors, but tokio::time::error::Elapsed did not carry the UnminedTxId needed to remove the timed-out entry. Each retained cancel_handles entry could hold a full Gossip::Tx(UnminedTx), while normal mined-transaction cleanup could not match attacker transactions and no periodic garbage collection or count cap existed. Sustained traffic therefore caused monotonic memory growth until swap pressure degraded the node or the operating system terminated the zebrad process for exhausting memory. This issue is fixed in version 4.5.0.

๐Ÿšจ CVE-2026-52735
ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, Zebra can accept a block that zcashd rejects because the P2SH signature-operation counter undercounts redeem scripts containing a disabled opcode followed by signature opcodes. In zebra-script/src/lib.rs, p2sh_input_sigop_count used the pure-Rust script::Code::sig_op_count path, whose try_fold parser stops at disabled opcodes such as OP_CODESEPARATOR and returns only the partial count accumulated before the error. The zcashd reference implementation continues static signature-operation counting through disabled opcodes, so an attacker can broadcast P2SH spends that Zebra counts below MAX_BLOCK_SIGOPS while zcashd counts above the 20,000-operation limit. If a Zebra miner includes those transactions, Zebra validators accept the block while zcashd validators reject it, creating a consensus chain split that affects network integrity and availability without requiring the attacker to produce a block. This issue is fixed in version 4.5.0.

๐Ÿšจ CVE-2026-52736
ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, a remote unauthenticated P2P peer can stall a Zebra node by racing an invalid block body against the valid canonical body for the same block header hash. ZIP-244 permits the attacker to mutate coinbase scriptSig authentication data while retaining the transaction identifiers, merkle root, and block header hash, so the poisoned body fails later commitment validation but shares the canonical hash. In zebra-state/src/service.rs, queue_and_commit_to_non_finalized_state recorded the hash in non_finalized_block_write_sent_hashes before contextual validation completed and did not remove it when the write task rejected the body. When the honest body later arrived, the cached hash caused KnownBlock::WriteChannel duplicate handling to suppress it, leaving the node stuck one height behind until restart or reorganization. This issue is fixed in version 4.5.0.

๐Ÿšจ CVE-2026-52737
ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, a malicious unauthenticated P2P peer can answer Zebra's outbound getblocks or FindBlocks request with a small two-hash inventory and then serve a syntactically valid block whose coinbase height is far above the local chain tip. In zebrad/src/components/sync/downloads.rs, BlockDownloadVerifyError::AboveLookaheadHeightLimit originally carried only the block height and hash, so handle_block_response could not attribute the failure to the advertising peer. The error then reached the restart-worthy default path in zebrad/src/components/sync.rs, cancelling all in-flight downloads from honest peers and imposing a 67-second sync restart delay on mainnet. Because the peer was neither scored nor disconnected, the peer could repeat the cycle indefinitely with minimal bandwidth and significantly degrade synchronization without corrupting state. This issue is fixed in version 4.5.0.

๐Ÿšจ CVE-2026-52738
ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, a consensus-valid block containing a long chain of transparent self-spends to one address can permanently halt Zebra nodes. In zebra-state/src/service/finalized_state/zebra_db/transparent.rs, the finalized-state writer originally applied every newly created output as a credit before applying any spent-output debit from the same block. That credit-first ordering can make the intermediate per-address balance exceed MAX_MONEY even though the final net balance is valid, causing an expect-based panic under the panic equals abort release profile. Because zcashd accepts the triggering block and Zebra encounters it again after every restart, the halt persists until patched software is deployed; exploitation requires mining the specially constructed block and temporarily committing sufficient ZEC to the self-spend chain. This issue is fixed in version 4.5.0.

๐Ÿšจ CVE-2026-52829
ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, an unauthenticated IPv4 peer can deterministically terminate a synced Zebra node using the default Linux dual-stack listener configuration. The handshake path canonicalized an IPv4-mapped IPv6 PeerSocketAddr such as ::ffff:127.0.0.1 to plain IPv4 before storing it through MetaAddr::new_connected, but the mempool misbehavior path forwarded the raw transient address to MetaAddrChange::UpdateMisbehavior. In zebra-network/src/meta_addr.rs, apply_to_meta_addr then compared the canonical address-book entry with the raw update address and reached its unexpected address mismatch assertion. After the misbehavior batch flush, panic equals abort terminated zebrad; the peer only needed to complete a P2P handshake and advertise an invalid mempool transaction. This issue is fixed in version 4.5.0.

๐Ÿšจ CVE-2026-65984
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. In 1.3.2 and earlier, POST /api/refresh in server/api/auth/index.js falls back from current user data to decoded.groups, including when the user is deleted or groups is zero, and POST /api/heartbeat in server/api/index.js re-signs inbound JWT claims without validating the current database record. An attacker who possesses a previously issued privileged refresh cookie or access token can continue minting privileged JWTs after account deletion, disablement, role removal, or demotion. Continued refresh-cookie rotation can extend the stale session and preserve unauthorized access to user management, project manipulation, runtime configuration, scripts, and backdoor-account creation. This issue is fixed in version 1.3.3.

๐Ÿšจ CVE-2026-65985
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. In 1.3.2 and earlier, the device-webapi-request Socket.IO handler in server/runtime/index.js permits an authenticated non-admin runtime user to control property.address, causing the FUXA server to issue an outbound HTTP or HTTPS request and return the response body to the requesting socket. The attacker can use the server as a read SSRF oracle against reachable internal services or cloud metadata endpoints, with impact depending on the FUXA host's deployment network. This issue is fixed in version 1.3.3.

๐Ÿšจ CVE-2026-67440
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. In 1.3.2 and earlier, the DEVICE_BROWSE, DEVICE_NODE_ATTRIBUTE, HOST_INTERFACES, and DEVICE_TAGS_REQUEST handlers in server/runtime/index.js return device-discovery, node-attribute, host-network-interface, and device-tag metadata without isSocketAdminAuthorized when secureEnabled is true. A remote unauthenticated or guest user can invoke these metadata-oriented Socket.IO events and collect system-discovery information that is not required for normal public HMI viewing, while ordinary device status, value, alarm, and dashboard events remain intentionally public. This issue is fixed in version 1.3.3.

๐Ÿšจ CVE-2026-67443
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. In 1.3.2 and earlier, the allowDashboard authorization gate in server/integrations/node-red/index.js calls authJwt.verify for /nodered without inspecting the decoded identity. When nodeRedEnabled is true, secureEnabled is true, and nodeRedAuthMode is secure, a remote unauthenticated attacker can obtain a signed guest token from POST /api/heartbeat and use it to access the RED.httpAdmin editor and flow deployment API. Because the Node-RED configuration has no second adminAuth gate, the attacker can deploy function nodes or invoke fuxa.runScript and runtime.scriptsMgr.runScript, gaining control of FUXA project data, configuration, scripts, filesystem-capable runtime helpers, and potentially operating-system commands when nodeRedUnsafeModules is enabled. This issue is fixed in version 1.3.3.

๐Ÿšจ CVE-2026-52817
Linuxfabrik Monitoring Plugins provides monitoring plugins for Icinga, Nagios, and related systems. Prior to version 5.1.0, the shipped assets/sudoers/Debian.sudoers policy allowed the nagios or icinga account to execute /usr/bin/apt-get as root without restricting its arguments. An attacker who already controls that monitoring account can supply the APT::Update::Pre-Invoke option to execute an arbitrary command while apt-get runs with root privileges, resulting in a root shell and complete compromise of the host. The vulnerable rule supports the check-plugins/deb-updates/deb-updates plugin, but it authorized arbitrary apt-get argument sequences rather than only the required apt-get update --quiet 2 command. This issue is fixed in version 5.1.0.

๐Ÿšจ CVE-2026-53759
linuxfabrik-lib provides Python modules for database access, caching, shell execution, and API integrations. Prior to version 4.2.0, db_sqlite.py created SQLite databases at predictable paths in the shared /tmp directory and followed attacker-created symbolic links at those paths. An attacker who controls a local monitoring account can create a symlink such as /tmp/linuxfabrik-monitoring-plugins-docker-stats.db and then trigger a sudo-authorized plugin, causing the root process to create or modify the symlink target. The primitive can overwrite arbitrary paths, cause denial of service, or manipulate an existing SQLite database through a crafted rollback journal or write-ahead log. The Monitoring Plugins integration also moved plugin caches through lib.db_sqlite.get_db_path() so they use the secured per-user directory. This issue is fixed in version 4.2.0.

๐Ÿšจ CVE-2026-55426
linuxfabrik-lib provides Python modules for database access, caching, shell execution, and API integrations, and Linuxfabrik Monitoring Plugins uses those modules to run external monitoring commands. From the earliest affected releases until linuxfabrik-lib 5.0.0 and Linuxfabrik Monitoring Plugins 6.0.0, check plugins embedded user-controlled values in command strings passed to lib.shell.shell_exec(), which split strings at pipe characters and executed the resulting commands. In check-plugins/restic-check/restic-check, the --repo parameter could inject a pipe-delimited command into a constructed restic invocation, and sudo-authorized execution allowed a compromised nagios or icinga account to run that command as root. The shared library also accepted command strings and a shell parameter, while numerous plugins constructed external commands from attacker-influenced arguments. The fixes require argv lists, always use shell=False, remove pipe splitting, and reject option-like positional values through lib.shell.safe_cli_value(). These issues are fixed in linuxfabrik-lib 5.0.0 and Linuxfabrik Monitoring Plugins 6.0.0.

๐Ÿšจ CVE-2026-67442
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Prior to 1.3.3, DELETE /api/roles removes role definitions through server/runtime/users/usrstorage.js but does not remove the deleted role identifier from each user's info.roles array or the runtime usersMap cache. If a permission configuration still references that identifier, an affected user can retain authorization rights that an administrator intended to revoke, causing residual privilege, inconsistent access-control state, and misleading audit results. This issue is fixed in version 1.3.3.
