What is CVE-2026-18046?

The Cookie Consent WordPress plugin prior to version 0.0.10 contains a significant flaw that allows authenticated users, even those with minimal privileges, to modify the geolocation service license key. This vulnerability arises due to insufficient enforcement of administrator-only capabilities on a RESTful endpoint, which leads to unauthorized overwrites of critical settings. Such unauthorized actions can disrupt geolocation-based cookie consent functionalities, compromising the plugin's effectiveness in managing user consent based on location.

Affected Version(s)

Cookie Consent 0.0.9 < 0.0.10

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.
