What to do
AI-suggested
Users should restrict author-level access to trusted users and monitor for suspicious activity involving Discourse API credentials. Review and sanitize the discourse_permalink custom field inputs to prevent sending credentials to untrusted hosts.
Description
The WP Discourse plugin for WordPress versions up to and including 2.5.9 has an information exposure vulnerability. The plugin sends Discourse API credentials unconditionally to any host specified in a post's discourse_permalink custom field during comment synchronization. This allows authenticated users with author-level access or higher to exfiltrate sensitive API credentials to attacker-controlled servers and potentially query internal services.
