CVE-2025-55009

Estado: AplazadaAlta (7.1)—

The AuthKit library for Remix provides convenient helpers for authentication and session management using WorkOS & AuthKit with Remix. In versions 0.14.1 and below, @workos-inc/authkit-remix exposed sensitive authentication artifacts — specifically sealedSession and accessToken — by returning them from the authkitLoader. This caused them to be rendered into the browser HTML.

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.

Acceso a red remota (AV:N) con privilegios (PR:L) sin interacción. Exposición de sealedSession y accessToken en HTML permite lectura de datos sensibles y credenciales de autenticación.

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.
