Deeper analysis
CVE-2026-4304 is a SQL injection vulnerability in the WeePie Cookie Allow plugin for WordPress, affecting all versions up to and including 3.4.11. The flaw arises from insufficient escaping of the user-supplied 'consent' parameter and lack of sufficient preparation in existing SQL queries, allowing attackers to append additional SQL queries. Published on 2026-05-05, it carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) and is classified under CWE-89.
Unauthenticated attackers can exploit this vulnerability remotely with low complexity and no user interaction required. By manipulating the 'consent' parameter, they can inject SQL payloads into ongoing queries, enabling extraction of sensitive information from the database while impacting only confidentiality.
