CWE-89Published: February 17, 2023· Updated: Jun 17, 2026
Official Description
The WP Coder – add custom html, css and js code plugin for WordPress is vulnerable to time-based SQL Injection via the ‘id’ parameter in versions up to, and including, 2.5.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers with administrative privileges to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
Technical Analysis
CVE-2023-0895 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), with a CVSS base score of 4.9.
From a weakness classification perspective (CWE-89): SQL injection vulnerabilities allow attackers to manipulate database queries, potentially exposing or modifying sensitive data.
