CVE-2026-55435 Â (opens in a new tab)How to fix?
Upgrade github.com/coder/coder/v2/aibridge to version 2.32.7, 2.33.8, 2.34.2 or higher.
Overview
Affected versions of this package are vulnerable to Incorrect Authorization due to insufficient validation in the IsAuthorized function. An attacker can maintain unauthorized access to AI Bridge LLM proxy endpoints by using previously issued, unexpired API tokens even after the associated user account has been suspended. This allows continued consumption of paid provider resources and invocation of injected tools until the token expires.
Workaround
This vulnerability can be mitigated by deleting the user's API keys via the DELETE /api/v2/users/{user}/keys endpoint upon suspension.
