Status: DeferredHigh (8.7)—

Serviio PRO 1.8 contains an improper access control vulnerability in the Configuration REST API that allows unauthenticated attackers to change the mediabrowser login password. Attackers can send specially crafted requests to the REST API endpoints to modify credentials without authentication.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
