phpMyFAQ vulnerabilities

phpMyFAQ before version 4.1.1 contains an XSS vulnerability in the regex-based SVG sanitizer. Attackers with edit_faq permission can upload a malicious SVG that uses HTML entity encoding in javascript: URLs within <a href> attributes, leading to arbitrary JavaScript execution and privilege escalation to full admin takeover.

An information disclosure vulnerability was found in phpMyFAQ prior to version 4.1.1 in the searchCustomPages() method. The escape() function uses real_escape_string(), which does not escape LIKE metacharacters (% and _), allowing an unauthenticated attacker to inject these characters and read unintended records.
