AI Analysis

Impact

A missing authorization check in phpMyFAQ's GroupController::deleteGroup allows authenticated administrators with GROUP_DELETE permission to specify a target groupId and permanently delete that group. This action removes the group and strips all members of any inherited rights, potentially compromising access controls and organizational structure.

Affected Systems

The vulnerability applies to thorsten's phpMyFAQ versions from 4.2.0-alpha through 4.2.0-beta. All installations using these versions and a non-SuperAdmin administrator account with GROUP_DELETE rights are susceptible. No specific patch release is included in the listed data.

Risk and Exploitability

The CVSS score of 7.0 represents moderate risk, while the EPSS score is not available, indicating no published exploitation data. The vulnerability is not listed in CISA KEV. The attack vector requires an authenticated user with GROUP_DELETE authority; the exploit does not require elevated network privileges or external access, making it readily exploitable within a compromised administrative account.

OpenCVE Recommended Actions

  • Upgrade phpMyFAQ to version 4.2.0‑beta or later where the missing authorization check is fixed.

  • Monitor administrative logs for deleteGroup API calls and verify that any group removals are legitimate.
