As published by the source; long descriptions are shortened.

Summary 12 endpoints in ConfigurationTabController.php use userIsAuthenticated() (login-only check) instead of userHasPermission(PermissionType::CONFIGURATIONEDIT). This allows any authenticated user — including ones with zero admin permissions — to enumerate system configuration metadata including the permission model, active template, cache backend, mail provider, and translation provider. Details The ConfigurationTabController contains 15 public endpoints. Three of them (list, save, uploadTheme) correctly enforce CONFIGURATIONEDIT permission: The remaining 12 only check that the user is logged in: The difference between these two methods is significant: There is no middleware or router-level authorization — the Kernel (Kernel.php) dispatches directly to controllers with only Language, Router, and Exception listeners. All authorization is at the controller method level. The 12 affected endpoints (all GET, all under /admin/api/): |

# Patch Next advisory brief: CVE-2026-45007

Advisory: phpMyFAQ's Missing CONFIGURATION_EDIT Permission Check on 12 Admin API Configuration Tab Endpoints Allows Information Disclosure by Any Authenticated User
IDs: CVE-2026-45007, GHSA-rm98-82fr-mcfx
Record: https://patchnext.com/advisories/cve-2026-45007 (revision 1, source checked 26 Oct 2026, 14:48 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: phpmyfaq/phpmyfaq 4.1.2; thorsten/phpmyfaq 4.1.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist phpmyfaq/phpmyfaq: affected <= 4.1.1; fixed in 4.1.2
- Packagist thorsten/phpmyfaq: affected <= 4.1.1; fixed in 4.1.2

## Suggested inspection (read-only)
- Packagist phpmyfaq/phpmyfaq: check the installed version with your package manager.
- Packagist thorsten/phpmyfaq: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on phpmyfaq/phpmyfaq, thorsten/phpmyfaq.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-rm98-82fr-mcfx (GitHub-reviewed advisory GHSA-rm98-82fr-mcfx lists affected ranges: Packagist thorsten/phpmyfaq >=0 =0 <=4.1.1)
