Summary
The Discussion Board WordPress forum plugin is affected, allowing logged-in users with at least subscriber-level access to store malicious scripts through their profile website field. These scripts can run in the browsers of anyone who views a forum topic containing the attacker's reply, potentially enabling session hijacking or actions performed on behalf of other users.

Read the original 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.
