What is CVE-2026-15368?

The User Profile Builder plugin for WordPress is vulnerable due to a flaw in the binding of automatic user login following registration. This security issue allows unauthenticated attackers to exploit the vulnerability by gaining an authenticated session of any existing user, including those with administrative privileges. This is particularly concerning for websites that utilize a supported but non-default configuration, which may inadvertently expose user sessions to unauthorized access.

Affected Version(s)

User Profile Builder 0 < 3.16.4

Exploit Proof of Concept (PoC)
