Technical Analysis
phpMyFAQ 4.2.0-alpha through versions before 4.2.0-beta have an information disclosure vulnerability caused by an inverted api.onlyPublicQuestions check in the OpenQuestionController. This allows unauthenticated attackers to send GET requests to the /api/v4.0/open-questions API endpoint and retrieve hidden open questions, including non-public moderation or internal questions and their associated usernames, which should be restricted from public access.
Potential Impact
The vulnerability permits unauthorized disclosure of sensitive information, specifically non-public questions and usernames, to unauthenticated attackers. This could lead to privacy violations and potential exposure of internal moderation content, but does not involve privilege escalation or code execution.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the /api/v4.0/open-questions endpoint or implement additional access controls to prevent unauthenticated access to non-public questions.
