CVE-2026-47132: Thorsten Phpmyfaq

Medium severity, CVSS 5.4. EPSS: 0.3% chance of exploitation in the next 30 days.

phpMyFAQ is an open source FAQ web application. Prior to version 4.2.0-alpha, an authenticated SQL LIKE wildcard injection vulnerability in phpMyFAQ’s chat user search allows any logged-in user to bypass the intended display-name search filter and enumerate active users. The endpoint escapes SQL string syntax but does not escape `%` and `_`, which remain active `LIKE` wildcards. Version 4.2.0-alpha patches the issue.

Affected products

• Thorsten Phpmyfaq: before 4.2.0-alpha (fixed in 4.2.0-alpha)
