CVE-2026-62418Network attack vector

Authenticated SSRF via Connector and Resource checks

Published Jul 20, 2026 · Updated Jul 20, 2026

SSRF in Apache Syncope allows remote authenticated users to make the server contact network services through Connector and Resource checks. The check methods accept submitted connector or resource connection parameters and attempt the configured connection, but Apache has not published the exact destination-validation failure. Low-privileged access to these operations is required, and affected releases are 3.0.0-M0 through 3.0.16, 4.0.0-M0 through 4.0.6, and 4.1.0-M0 through 4.1.1; response visibility and protocol scope are undisclosed.
