🚨 CVE-2026-54388
Tinyproxy through 1.11.3, fixed in commit 364cdb6, fails to reject requests containing multiple Content-Length headers with differing values, forwarding all duplicate headers to the backend while using the first value to determine how many request body bytes to consume. Remote attackers can desynchronize the proxy and backend parser state, allowing injection of arbitrary HTTP requests to the backend to enable cache poisoning, access control bypass, and request hijacking.

🚨 CVE-2026-55199
libssh2 through 1.11.1, fixed in commit 1762685, contains a pre-authentication denial of service vulnerability in the SSH_MSG_EXT_INFO handler in src/packet.c that allows a malicious SSH server to cause a client CPU exhaustion loop by sending a crafted extension count value. A malicious server can set nr_extensions to 0xFFFFFFFF during key exchange, causing the client to spin in a tight CPU loop for over 60 seconds because return values from _libssh2_get_string() are unchecked and the session timeout does not apply to CPU-bound loops.

🚨 CVE-2026-55200
libssh2 through 1.11.1, fixed in commit 7acf3df contains an out-of-bounds write vulnerability in ssh2_transport_read() that fails to enforce upper bounds on packet_length field. Remote attackers can send crafted SSH packets with excessively large packet_length values to corrupt heap memory and achieve remote code execution.

🚨 CVE-2026-55201
Evil-WinRM through 3.9, fixed in commit 6ecd570, contains a path traversal vulnerability in the download_dir() function that allows a rogue or compromised remote Windows server to write files outside the intended download directory by returning filenames with traversal sequences from Get-ChildItem command output that are passed unsanitized to File.join(). Attackers controlling the remote server can exploit this to overwrite sensitive client-side files such as SSH authorized_keys or shell configuration files, achieving persistent access or privilege escalation on the client machine.

🚨 CVE-2026-50262
An out-of-bounds read flaw was found in the X.Org X server and Xwayland in __glXDisp_ChangeDrawableAttributes(). A wrong size validation check can read a client-controlled number of bytes, exceeding the request buffer, leading to information disclosure. A write path also exists but requires byte-swapped clients which is disabled by default.

🚨 CVE-2026-50263
A use-after-free flaw was found in the X.Org X server and Xwayland in CreateSaverWindow(). A client can trigger a use-after-free read after changing window attributes and forcing the screen saver, leading to information disclosure.

🚨 CVE-2026-32193
Improper limitation of a pathname to a restricted directory ('path traversal') in Microsoft Azure Kubernetes Service allows an authorized attacker to execute code locally.

🚨 CVE-2026-53840
OpenClaw before 2026.5.12 contains an information disclosure vulnerability in streamable-http MCP servers that forwards operator-configured custom headers during cross-origin redirects. Attackers controlling or compromising an MCP endpoint can redirect requests to exfiltrate sensitive headers like API keys or tenant-routing credentials to attacker-controlled origins.

🚨 CVE-2026-53841
OpenClaw before 2026.5.12 contains a cross-site scripting vulnerability in exported session HTML that preserves unsafe javascript: and data: links in generated content. Attackers can execute browser-side scripts if a trusted operator opens the exported file and activates a malicious link.

🚨 CVE-2026-53842
OpenClaw before 2026.5.2 contains an environment variable injection vulnerability allowing workspace .env files to influence Python runtime selection through CLOUDSDK_PYTHON during Gmail setup gcloud execution. Attackers with repository access can manipulate the CLOUDSDK_PYTHON variable to execute setup through unintended local Python paths, potentially enabling arbitrary code execution.

🚨 CVE-2026-53843
OpenClaw before 2026.5.26 contains an authorization bypass vulnerability where a surviving pairing-scoped device session can re-establish node token authority after revocation. Attackers with a paired device can regain WebSocket node-level access without renewed approval, weakening revocation controls and maintaining unauthorized access longer than intended.

🚨 CVE-2026-53844
OpenClaw before 2026.4.29 contains a session visibility check bypass vulnerability in shared memory search that allows authenticated callers to access memory entries without proper authorization. Attackers can skip session visibility guards on the search path to retrieve memory entries that should not be visible to their session.

🚨 CVE-2026-53845
OpenClaw before 2026.5.6 contains a hook bypass vulnerability where skill commands routed through the affected dispatch path skip before-tool-call hook coverage. Attackers can exploit this by sending skill commands through the vulnerable dispatch path to bypass hook-based auditing and policy enforcement mechanisms.

🚨 CVE-2026-53846
OpenClaw before 2026.4.29 contains a path traversal vulnerability in the install helper that allows workspace .env files to override the npm_execpath configuration used for bundled runtime dependency installation. Attackers with workspace access can execute unintended local package-manager executables during dependency setup to compromise the build environment.

🚨 CVE-2026-53847
OpenClaw before 2026.5.6 contains a privilege escalation vulnerability in the Active Memory write scope that allows Gateway operators with operator.write access to modify global configuration without requiring operator.admin privileges. Attackers with operator.write access can exploit insufficient scope validation to apply unauthorized configuration changes beyond the intended write scope.

🚨 CVE-2026-53848
OpenClaw before 2026.5.26 contains an exec allowlist bypass vulnerability allowing authenticated operators to execute wrapper-level side effects outside allowlisted command intent. Attackers can craft command requests that bypass allowlist validation by leveraging transparent command wrappers to perform unintended operations.

🚨 CVE-2026-53849
OpenClaw before 2026.5.7 contains a privilege escalation vulnerability where the allowFrom feature improperly validates Discord account identity using mutable display names instead of immutable user IDs. Attackers with Discord accounts can change their display name to match a policy entry and gain unauthorized agent access intended for another Discord identity.

🚨 CVE-2026-53850
OpenClaw before 2026.4.25 contains a control scope enforcement bypass vulnerability in the focus command that allows authenticated callers to execute the command without proper authorization checks. Attackers can trigger the focus command to change focus state outside intended caller authority, potentially enabling unauthorized operations depending on gateway configuration and input trust levels.

🚨 CVE-2026-53851
OpenClaw before 2026.5.12 contains a notification bypass vulnerability allowing Slack reaction events to enter the agent pipeline despite disabled reaction notifications. Attackers can trigger unintended agent processing by sending reaction events when the feature is enabled, potentially leading to unauthorized processing of lower-trust input.
