Incomplete fix for CVE-2026-32812: SSRF in admidio

Published May 7, 2026 CVSS 3.1 · 6.8 Medium EPSS < 1% KEV · Not listed
Description
Admidio is an open-source user management solution. Prior to version 5.0.9, the incomplete SSRF fix in Admidio's fetch_metadata.php validates the resolved IP address but passes the original hostname-based URL to curl_init(), leaving a DNS rebinding TOCTOU window that allows redirecting requests to internal IPs. This issue has been patched in version 5.0.9.
