What is CVE-2026-87835?

The Front End Users WordPress plugin, up to version 3.2.35, contains an access control vulnerability that fails to limit the account attributes a visitor can modify during front-end registration. This allows unauthenticated users to assign themselves arbitrary membership levels, circumventing established content restrictions. As a result, these users can approve and confirm their accounts without the necessary permissions, leading to potential misuse of functionality and unauthorized access.

Affected Version(s)

Front End Users 0 <= 3.2.35

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
