Administrator SSRF and file disclosure via URL fetch
Published Mar 20, 2026 · Updated Mar 20, 2026
SSRF in Admidio 5.0.0 through 5.0.6 allows remote authenticated users to read local files and internal responses through the SSO Metadata API. The fetch_metadata.php endpoint validates an arbitrary url parameter only as a syntactically valid URL, passes it to file_get_contents(), and returns the response body verbatim. Administrator access is required; readable server files, internal services, and cloud metadata are exposed without reported write or service-interruption impact.
