What is CVE-2025-1435?
CVE-2025-1435 is a medium-severity vulnerability in johnjamesjacoby bbPress, published on 5 Mar 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
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.
Weakness: CWE-352
