CVE-2026-91864

Estado: AnalizadaAlta (7.5)—

A specially crafted WS-Policy document can pack unlimited content inside a policy assertion, which Neethi copies into memory without counting it against its size limits, exhausting the heap (denial of service). Users are recommended to upgrade to version 3.2.4, which fixes this issue.

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 AV:N/AC:L/PR:N sin interacción permite explotación remota directa (T1190). WS-Policy malformado causa exhaustión de heap (DoS de aplicación, T1499.004).

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.
