Prior to version 4.9.6, Admin-configured OIDC token_url and user_info_url in includes/oidc/handle_oidc_callback.php:18-49 are used directly in curl_init() with zero SSRF filtering. Unlike logo/webhook URLs which have validate_webhook_url_for_ssrf(), OIDC URLs bypass all protections. Admin sets URL to http://169.254.169.254/latest/meta-data/ for cloud metadata access or internal network pivoting. This issue has been patched in version 4.9.6.","published":"2026-08-31T21:17:17.000Z","lastModified":"2026-09-08T21:11:32.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"4.0","score":8.5,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-918"],"affected":[],"epss":{"score":0.0054,"percentile":0.45252,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.54%).
