CVE-2026-4794

Estado: AnalizadaBaja (2.1)—

Multiple cross-site scripting (XSS) vulnerabilities in PaperCut NG/MF before 25.0.10 allow authenticated administrator users to inject arbitrary web script or HTML code via different UI fields. This could be used to compromise other admininistrator's sessions or perform unauthorized actions via the administrator's authenticated context (e.g. requires an active login session).

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).
