What is CVE-2026-13598?

The RestrictMate plugin for WordPress prior to version 1.3.0 contains a flaw that fails to properly restrict the user role during the account registration process. This oversight permits unauthenticated attackers to create a new account with administrative privileges, enabling them to gain unauthorized access to the site's backend. Consequently, the attacker can manipulate site settings, install malicious software, or fully compromise the WordPress site.

Affected Version(s)

RestrictMate 0 < 1.3.0

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.
