CVE-2026-107765 Details
Description
The Discussion Board – WordPress Forum Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.6.0 via the user profile Website (user_url) field. This is due to insufficient output escaping in the ctdb_filter_comment_author_name() callback hooked to get_comment_author_link, which interpolates the raw user_url value into a single-quoted href attribute without esc_url() or esc_attr(). This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses a Discussion Board topic containing the attacker's reply.
A stored cross-site scripting vulnerability has been identified in the Discussion Board – WordPress Forum Plugin, affecting versions through 2.6.0. The issue arises from inadequate output escaping in the 'ctdb_filter_comment_author_name' function, which is linked to 'get_comment_author_link'. This function improperly inserts the raw 'user_url' value into a single-quoted href attribute without using 'esc_url()' or 'esc_attr()'. As a result, authenticated attackers with subscriber-level access or higher can inject arbitrary web scripts into pages. These scripts will execute whenever a user views a Discussion Board topic that includes the attacker's reply.
Users are advised to update the Discussion Board – WordPress Forum Plugin to version 2.6.1 or a newer patched version.
