Technical summary

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().

Defensive priority

Defenders should prioritize verifying and updating the Discussion Board – WordPress Forum Plugin to a version beyond 2.6.0, reviewing user profile Website fields for suspicious input, and ensuring proper output escaping for user-supplied data in comments.

Recommended defensive actions
