CVE-2026-24422: phpMyFAQ: Public API endpoints expose emails and invisible questions

phpMyFAQ is an open source FAQ web application. In versions 4.0.16 and below, multiple public API endpoints improperly expose sensitive user information due to insufficient access controls. The OpenQuestionController::list() endpoint calls Question::getAll() with showAll=true by default, returning records marked as non-public (isVisible=false) along with user email addresses, with similar exposures present in comment, news, and FAQ APIs. This information disclosure vulnerability could enable attackers to harvest email addresses for phishing campaigns or access content that was explicitly marked as private. This issue has been fixed in version 4.0.17.

Security readout for executives and security teams

Plain-English summary

CVE-2026-24422 affects phpMyFAQ versions 4.0.16 and earlier. Public API endpoints can expose user email addresses and FAQ content marked non-public. The main business risk is information leakage that could support phishing or reveal private draft/internal questions. The vendor advisory states the issue is fixed in version 4.0.17.

Executive priority

Treat as a near-term remediation item, especially for public phpMyFAQ sites. The issue is not described as actively exploited and has moderate CVSS severity, but it can expose emails and private content. Upgrade during the next scheduled security maintenance window, sooner if sensitive internal content is stored in phpMyFAQ.

Technical view

The vulnerability is an improper access control information disclosure issue, classified as CWE-200. Public API endpoints, including OpenQuestionController::list(), may return records intended to be hidden because Question::getAll() is called with showAll=true by default. Similar exposure is reported in comment, news, and FAQ APIs. CVSS is 5.3: network-accessible, low complexity, no authentication required, confidentiality impact only.

Likely exposure

Organizations running internet-accessible phpMyFAQ versions below 4.0.17 are the likely exposure group. Risk is higher where public APIs contain user emails, unpublished questions, private content, comments, news, or FAQ data that should not be visible anonymously.

Exploitation context

Sources do not report active exploitation, and the CVE is not listed as CISA KEV in the provided data. Exploitation would require only network access to affected public API endpoints, but the documented impact is limited to information disclosure, not code execution or service disruption.

Researcher notes

The public advisory identifies multiple API exposure paths but the provided evidence centers on information disclosure. Do not assume broader compromise without separate findings. Validation should focus on version confirmation, anonymous API reachability, and whether non-public records or email addresses are returned in affected deployments.

Mitigation direction

  • Upgrade phpMyFAQ to version 4.0.17 or later.
  • Review vendor advisory GHSA-j4rc-96xj-gvqc for current guidance.
  • Restrict public API exposure where business requirements allow.
  • Review exposed FAQ, news, comment, and question data for sensitive content.

Validation and detection

  • Inventory phpMyFAQ deployments and identify versions below 4.0.17.
  • Confirm whether affected public API endpoints are reachable anonymously.
  • Review API responses for emails or non-public content exposure.
  • Check logs for unusual anonymous API enumeration patterns.

Exposure of Sensitive Information to an Unauthorized Actor

Exposure of Sensitive Information to an Unauthorized Actor represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
