CVE-2026-4276

Estado: AnalizadaAlta (7.5)—

LibreChat RAG API, version 0.7.0, contains a log-injection vulnerability that allows attackers to forge log entries.

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.

Inyección de logs en API expuesta en red (AV:N, PR:N) permite falsificar registros. CWE-94 sugiere ejecución indirecta, pero el texto especifica manipulación de logs (integridad), no ejecución de comandos: T1565.001 (falsificación de datos en registros).

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.
