Vulnerability from cvelistv5 – Published: 2026-08-11 16:40 – Updated: 2026-08-11 18:39

Title

Audiobookshelf: Refresh Token Accepted on Resource Endpoints

Summary

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.

Severity

5.3 (Medium)
