CVE-2025-62614
BookLore Media API Authentication Bypass
Description
BookLore is a self-hosted web app for organizing and managing personal book collections. In versions 1.8.1 and prior, an authentication bypass vulnerability in the BookMediaController allows any unauthenticated user to access and download book covers, thumbnails, and complete PDF/CBX page content without authorization. The vulnerability exists because multiple media endpoints lack proper access control annotations, and the CoverJwtFilter continues request processing even when no authentication token is provided. This enables attackers to enumerate and exfiltrate all book content from the system, bypassing the intended download permissions (canDownload) entirely. This issue has been patched via commit b226c43.

Action Type Old Value New Value Added Translation Title: booklore-app, Description: BookLore es una aplicación web autoalojada para organizar y gestionar colecciones de libros personales. En las versiones 1.8.1 y anteriores, una vulnerabilidad de omisión de autenticación en el BookMediaController permite a cualquier usuario no autenticado acceder y descargar portadas de libros, miniaturas y contenido completo de páginas PDF/CBX sin autorización. La vulnerabilidad existe porque múltiples puntos finales de medios carecen de anotaciones de control de acceso adecuadas, y el CoverJwtFilter continúa el procesamiento de la solicitud incluso cuando no se proporciona ningún token de autenticación. Esto permite a los atacantes enumerar y exfiltrar todo el contenido de los libros del sistema, omitiendo por completo los permisos de descarga previstos (canDownload). Este problema ha sido parcheado mediante el commit b226c43. -
