CVE-2026-111936

Description

Sigma File Manager through 2.2.0 contains a server-side request forgery vulnerability because validate_remote_url() in security.rs never checks resolved IP addresses for extension download commands. A malicious extension or catalog entry can use hostnames resolving to loopback, private, or cloud metadata addresses to read internal responses via files written to the extension directory.
