CVE-2007-5795

Estado: ModificadaMedia (6.3)—💥 Exploit

The hack-local-variables function in Emacs before 22.2, when enable-local-variables is set to :safe, does not properly search lists of unsafe or risky variables, which might allow user-assisted attackers to bypass intended restrictions and modify critical program variables via a file containing a Local variables declaration.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
