CVE-2026-22904

Estado: AplazadaCrítica (9.8)—

Improper length handling when parsing multiple cookie fields (including TRACKID) allows an unauthenticated remote attacker to send oversized cookie values and trigger a stack buffer overflow, resulting in a denial‑of‑service condition and possible remote code execution.

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.

Vector CVSS AV:N/AC:L/PR:N/UI:N indica explotación remota sin autenticación (T1190). CWE-121 (buffer overflow) permite ejecución de código (T1059) y denegación de servicio (T1499.004 por crash).

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.
