CVE-2026-91867

Estado: AnalizadaMedia (4.3)—

When Neethi fetches a remote policy reference, it only limits the time per read, not the whole transfer, so a server that trickles bytes slowly can keep the fetch alive indefinitely and tie up the calling thread (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.

Explotación remota que requiere interacción del usuario (UI:R) al fetchar política remota. Trickling ataque causa DoS por agotamiento de recursos del hilo (thread exhaustion).

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.
