Auth bypass in Advplyr Audiobookshelf
CVE-2026-73085
Audiobookshelf is a self-hosted audiobook and podcast server. Prior to 2.36.0, the jwtAuthCheck function in server/auth/TokenManager.js treats JWTs with the refresh token type as bearer access tokens on API and WebSocket resource endpoints such as /api/me instead of restricting them to /auth/refresh, allowing refresh tokens to authenticate as the associated users. This issue is fixed in version 2.36.0.
