MEDIUM 5.3REMOTEDOWNGRADE

CVE-2026-34973 is a medium-severity flaw (CVSS 5.3) affecting phpmyfaq. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

phpMyFAQ is an open source FAQ web application. Prior to version 4.1.1, the searchCustomPages() method in phpmyfaq/src/phpMyFAQ/Search.php uses real_escape_string() (via escape()) to sanitize the search term before embedding it in LIKE clauses. However, real_escape_string() does not escape SQL LIKE metacharacters % (match any sequence) and _ (match any single character). An unauthenticated attacker can inject these wildcards into search queries,
