CVE-2026-81821

Estado: AplazadaAlta (8.3)—

The vulnerability, if exploited, could allow a miscreant with read access to PIMBoards project files to decrypt and view sensitive information.

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.

AV:L con PR:L indica escalada local de privilegios. CWE-321 (uso de clave criptográfica débil) permite leer datos sensibles de archivos de proyecto accesibles. El vector VC:H confirma impacto de confidencialidad.

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.
