CVE-2026-96271

Estado: AplazadaAlta (7.1)—

Photoview through 2.4.0 contains an authorization bypass vulnerability in the shareAlbum GraphQL mutation that allows authenticated users to create share links for albums owned by other users. Attackers can supply arbitrary album IDs to generate working share tokens for victim albums, exposing photos and sub-albums to anyone with the link while retaining indefinite control over token settings.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vulnerabilidad de bypass de autorización en API GraphQL que permite a usuarios autenticados manipular datos ajenos (crear tokens de compartición para álbumes de otros). AV:N/PR:L/UI:N indica explotación remota con privilegios limitados sin interacción.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
