CVE-2023-1761Network attack vector

Authenticated script injection via unsanitized comments

Published Mar 31, 2023 · Updated Feb 11, 2025

Cross-site scripting in phpMyFAQ before 3.1.12 allows remote authenticated users to inject script through comment fields. The ajaxservice comment path stored nl2br-transformed text without stripping tags, while Comments rendered usernames without HTML encoding. A low-privileged account can place script in comment output, enabling browser-context data access or actions when the affected content is rendered.
