The bbPress plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.6.11. This is due to missing or incorrect nonce validation on the bbp_user_add_role_on_register() function. This makes it possible for unauthenticated attackers to elevate their privileges to that of a bbPress Keymaster via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. Rather than implementing a nonce check to provide protection against this vulnerability, which would break functionality, the plugin no longer makes it possible to select a role during registration.
CVE-2025-1435 is a medium severity with CVSS 6.3 Cross-Site Request Forgery issue affecting the Plugin bbPress. It affects Versions up to 2.6.11 and is fixed in 2.6.12.
CVE-2025-1435 is tracked for the Plugin bbPress as medium severity with CVSS 6.3. The affected range is Versions up to 2.6.11. Update bbPress to 2.6.12 or newer where that version is compatible with the site.
