CVE-2026-55435Network attack vector

Continued AI Bridge access via suspended-user tokens

Published Jul 7, 2026 · Updated Jul 7, 2026

Incorrect authorization in affected Coder releases allows remote authenticated users to retain AI Bridge access after account suspension. The affected ranges are 2.30.0 through 2.32.6, 2.33.0 through 2.33.7, and 2.34.0 through 2.34.1; Server.IsAuthorized in coderd/aibridgedserver checks token validity and deleted or system status but omits whether the account is suspended. An already-issued unexpired API key is required; continued calls can consume paid LLM resources and invoke enabled injected MCP tools.
