CVE-2026-28676

Estado: AnalizadaAlta (8.8)—

OpenSift is an AI study tool that sifts through large datasets using semantic search and generative AI. Prior to version 1.6.3-alpha, multiple storage helpers used path construction patterns that did not uniformly enforce base-directory containment. This created path-injection risk in file read/write/delete flows if malicious path-like values were introduced. This issue has been patched in version 1.6.3-alpha.

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.

CWE-22 (path traversal) en servicio remoto con PR:L permite lectura/escritura/eliminación de archivos. Acceso local requerido (PR:L) → T1210. Impactos: lectura (T1005), manipulación (T1565) y potencial escalada de privilegios.

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.

Esto creaba riesgo de inyección de rutas en los flujos de lectura/escritura/eliminación de archivos si se introducían valores maliciosos similares a rutas. Este problema ha sido parcheado en la versión 1.6.3-alpha."
