CVE-2025-11983 Details
Description
The WP Discourse plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 2.5.9. This is due to the plugin unconditionally sending Discourse API credentials (Api-Key and Api-Username headers) to any host specified in a post's discourse_permalink custom field during comment synchronization. This makes it possible for authenticated attackers, with author-level access and above, to exfiltrate sensitive Discourse API credentials to attacker-controlled servers, as well as query internal services and potentially perform further attacks.
A vulnerability allowing information exposure has been identified in the WP Discourse plugin for WordPress, affecting all versions through 2.5.9. The issue arises because the plugin automatically sends Discourse API credentials, including the Api-Key and Api-Username, to any host specified in a post's discourse_permalink custom field during comment synchronization. This behavior enables authenticated attackers with author-level access or higher to exfiltrate sensitive Discourse API credentials to servers under their control, potentially allowing further exploitation by querying internal services or conducting additional attacks.
Users are advised to update the WP Discourse plugin to version 2.6.0 or later, where this vulnerability has been patched.
