CVE-2026-84994

Google OSS Agent Mesh (SAM) versions 0.1.0-alpha.1 through 0.1.0-alpha.8 contain Missing Authorization (CWE-862) and Insecure Default Initialization (CWE-1188) in the MCP proxy and OIDC registration flow. Public disclosure of OIDC configuration via GET /info and auto-enrollment of any valid OIDC token holder via POST /register without claim filtering or ban checks allow a remote attacker to self-enroll into the mesh and invoke arbitrary tools across all connected MCP backend nodes.

Google OSS Agent Mesh (SAM) versions 0.1.0-alpha.1 through 0.1.0-alpha.2 contain Missing Authentication for Critical Function (CWE-306) and Missing Authorization (CWE-862) in the /libp2p-http ingress server. An unauthenticated remote libp2p peer can bypass Biscuit capability policy enforcement and invoke arbitrary registered backend services, including command/stdio-backed MCP servers, A2A, and inference endpoints.

A vulnerability exists in the Web Server default connection ports under the process name GeoWebServer.exe.

Vanus 0.8.0 through 0.9.0 contains a default credentials vulnerability that allows unauthenticated remote attackers to gain cluster-admin access by using the hardcoded admin token. Attackers can send the fixed Bearer token to the gateway gRPC proxy port to manage namespaces, eventbuses, users, tokens, and role bindings, and read or publish events.

The Conversational Forms for ChatBot plugin (up to version 1.5.1) is vulnerable to deserialization of untrusted data, allowing object injection. An attacker can supply malicious data that gets deserialized by the application.

The OttoKit plugin (up to version 1.1.40) has an incorrect privilege assignment vulnerability that allows privilege escalation. An attacker can exploit this to gain higher privileges.

The Booktics plugin (up to version 1.0.29) is vulnerable to SQL injection due to improper neutralization of special elements in SQL commands. An attacker can execute arbitrary SQL queries.

phpMyFAQ 4.0.0 before 4.1.9 contains an authentication bypass vulnerability where WebAuthn registration endpoints attach credentials to any account without authentication or challenge validation. Attackers can stage a victim username, submit a forged fmt=none attestation to register a passkey, then log in bypassing passwords and TOTP for account takeover.

The LearnPress plugin for WordPress in versions up to and including 4.4.10 is vulnerable to PHP Object Injection via deserialization of untrusted input from the 'checkout-email' request parameter during the checkout AJAX action. The value passes through sanitize_text_field(), which does not strip serialized object syntax, is stored in the LearnPress session table, and later fed to unserialize() without an allowed_classes restriction.

The LatePoint plugin for WordPress in versions up to and including 5.7.4 is vulnerable to Authentication Bypass via Race Condition in the verifyOTP function. The OTP attempts counter is updated non-atomically without a WHERE attempts < 10 guard and without a row lock, creating a TOCTOU window that lets concurrent requests bypass the 10-attempt lockout.
