CVE-2026-111936 Details
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.
A server-side request forgery (SSRF) vulnerability has been identified in Sigma File Manager versions through 2.2.0. The issue arises because the function validate_remote_url() in security.rs fails to check resolved IP addresses for extension download commands. This oversight allows a malicious extension or a harmful entry in a third-party extension catalog to exploit the vulnerability by using hostnames that resolve to loopback, private, or cloud metadata addresses. Such an extension could read internal responses by writing files to its extension directory and then accessing those files.
Users can update to Sigma File Manager version 2.2.1 or later, where this vulnerability has been addressed.
