🚨 CVE-2026-11718
An authentication bypass vulnerability exists in the generic opaque token validation path (validateOpaqueToken) of googleapis/mcp-toolbox.

When the toolbox validates an opaque token via an OAuth 2.0 introspection endpoint (RFC 7662), it decodes the response into an introspectResp struct. However, the subsequent claim-checking logic (validateClaims) evaluates the issuer condition as if a.issuer != "" && iss != "". If the external OAuth provider's introspection response omits the optional iss (issuer) field completely, the variable iss defaults to an empty string. This causes the conditional block to evaluate to false and be skipped silently. Consequently, the application accepts tokens issued by unauthorized or unintended third-party identity providers.

🚨 CVE-2026-11719
An authenticated authorization bypass vulnerability exists in MCP Toolbox for Databases due to missing scope enforcement across older protocol handlers.

While the 2025-11-25 protocol version handler correctly enforces per-tool restrictions defined by scopesRequired, older supported protocol versions (2025-06-18, 2025-03-26, and 2024-11-05) omit this check. An authenticated client with low-privilege tokens (e.g., read) can bypass the intended per-tool scope restrictions and execute high-privilege tools (e.g., admin) simply by specifying an older protocol version in the MCP-Protocol-Version header, or by omitting the header entirely (which causes the server to default to the vulnerable 2024-11-05 handler).

🚨 CVE-2026-11958
Local privilege escalation by loading DLLs from a shared temporary directory in ANSSI’s DFIR-ORC, versions 10.2.7 and prior. An attacker with prior access to the system, can place a malicious DLL in C:\Windows\Temp and wait for the application to be executed. Because DFIR-ORC is extracted and executed from that location with administrative privileges, the malicious library can be loaded automatically, allowing the attacker to gain administrator privileges on the affected machine.

🚨 CVE-2026-12039
Docker Sandboxes (sbx) enforces an HTTP/S-only egress allowlist but does not apply it to DNS resolution: the per-network embedded DNS server forwards any queried name to the host resolver whenever the network is internet-connected, without consulting the policy. A workload inside a sandbox, which the threat model treats as untrusted, can therefore encode data into DNS labels for an attacker-controlled domain and exfiltrate it through a DNS covert channel, bypassing the configured allowlist.

🚨 CVE-2026-12527
A broken authorization boundary in the RTSP media delivery pipeline of Shenzhen Liandian Communication Technology LTD V380 IP Camera firmware AppFHE1_V1.0.6.020230803 enables unauthenticated network actors to bypass the device’s credential-enforced live-view workflow and directly retrieve real-time video stream data.

🚨 CVE-2026-12539
Docker Sandboxes (sbx) blocks ICMP egress with an authorizer applied only at network-creation time, and does not re-apply it to networks rebuilt from disk when the Docker daemon restarts, so a restart-surviving sandbox forwards ICMP to arbitrary hosts. A workload inside a sandbox, which the threat model treats as untrusted, can therefore defeat the documented ICMP egress block to perform network reconnaissance and exfiltrate data over an ICMP covert channel, regardless of the configured allowlist.

🚨 CVE-2026-40456

🚨 CVE-2026-40457
A Reflected Cross-Site Scripting (XSS) vulnerability exists in LMS (LAN Management System) before commit 9c5651b in the "dbrecover.php" and "netremap.php" modules where unsanitized GET parameters are directly embedded into HTML output. This allows an attacker to inject arbitrary JavaScript when an authenticated user clicks a crafted link, provided the required conditions (such as a network defined in the system) are met.

🚨 CVE-2026-42487
HVM guest I/O port accesses are subject to either emulation or at least
translation. Translations are managed by the device model (via
XEN_DOMCTL_ioport_mapping), and hence the linked list used may changed
at any time. Traversal of those lists (while handling guest I/O port
accesses) therefore needs synchronizing with updates, which was missing
so far.

🚨 CVE-2026-42488
Some shadow paging errors paths will switch the page-tables without
updating the currently running vCPU reference. This causes a mismatch
between the loaded page-tables and the mapcache metadata which can lead
to corruption of the mapcache.

🚨 CVE-2026-42489
[This CNA information record relates to multiple CVEs; the
text explains which aspects/vulnerabilities correspond to which CVE.]

To create and manage guests, domctl operations are used by the control
domain, a possible Xenstore domain, or by a domain controlling a
particular guest. Some of these operations may not be executed in
parallel, so a system-wide lock is used. The way that lock is acquired
is, however, not providing any fairness. This is CVE-2026-42489.

Furthermore, with XSM/Flask in use, the lock acquire will, for some
operations, occur ahead of any permission checking. This is
CVE-2026-42490.

🚨 CVE-2026-50141
Woodpecker is a CI/CD engine. Starting in version 3.0.0 and prior to version 3.14.1, a vulnerability in Woodpecker CI's gRPC layer allowed any authenticated agent to impersonate any other agent on the same server by injecting a forged `agent_id` value into outgoing gRPC metadata. The server correctly verified the JWT token but then discarded the verified agent identity in favor of the client-supplied value. Version 3.14.1 patches the issue. As a workaround, disable org agents (`WOODPECKER_DISABLE_USER_AGENT_REGISTRATION=true`) and delete existing ones.

🚨 CVE-2026-54419
claudiopizzillo PIAF-HMS (PBX-In-A-Flash Hotel Management System; no released versions, latest commit 389d2633441b65ced1c104212cd62be2bfca21e5) contains multiple unauthenticated SQL injection vulnerabilities. The application has no authentication mechanism and passes user-supplied HTTP parameters directly into deprecated mysql_query() calls via string concatenation, without sanitization, escaping, or parameterization. Affected sinks include rooms.php (DELETE FROM Rooms WHERE ID = $_GET['ID'], unquoted numeric context), checkuser.php (WHERE Ext = '$_GET["Ext"]'), ec.php (date/extension parameters in a WHERE), checkin.php and wakeup.php ($_POST values into INSERT statements), bills.php ($_POST fields built into a WHERE clause), and rates.php and checkout.php. A remote, unauthenticated attacker can inject arbitrary SQL to read, modify, or delete arbitrary records in the backing database (e.g. rooms.php?ID=1 OR 1=1 deletes all room records). Note: queries run via the legacy mysql_* extension, which does not permit stacked statements.
