What is CVE-2026-89324?

The Basel Post Types plugin for WordPress is vulnerable due to a coding error in the defined() function related to SECURE_AUTH_SALT. This flaw allows unauthenticated attackers to bypass authentication checks entirely, enabling them to impersonate any existing user, including administrators. The issue arises because a hardcoded salt value is exposed in the theme source, allowing attackers to compute valid authentication signatures offline. Successful exploitation necessitates that WooCommerce is active and that at least one social login provider is configured.

Affected Version(s)

Basel Post Types 0 <= 1.18

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.
