CVE-2026-6649Public exploitNetwork attack vector

Authenticated SSRF via unchecked starts parameter

Published Apr 20, 2026 · Updated Apr 20, 2026

Server-side request forgery in Qibo CMS 1.0 allows remote authenticated users to make server-originated requests via the starts parameter. The /index/image/headers endpoint uses the attacker-controlled value as an outbound-request destination without adequate validation. Low-privileged CMS access is required, and resulting requests can reach network resources available to the CMS server; further impact is undisclosed.
