CVE-2026-42884

Full vulnerability record from the local CVENow database.

Description

Audiobookshelf is a self-hosted audiobook and podcast server. Prior to 2.32.2, the GET /api/collections and GET /api/collections/:id endpoints return collections from all libraries without checking whether the requesting user has access to each collection's library. An authenticated user with access to any library can enumerate and read collections (including full book metadata) from libraries they are explicitly restricted from accessing. This vulnerability is fixed in 2.32.2.
