CVE-2025-22868

Estado: AnalizadaAlta (7.5)—

An attacker can pass a malicious malformed token which causes unexpected memory to be consumed during parsing.

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 sin autenticación (PR:N) indica exposición de aplicación web. Consumo de memoria anómalo sugiere DoS por agotamiento de recursos.

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.
