Detailsinfo

A vulnerability was found in Easy PHP Settings Plugin up to 1.0.4 on WordPress. It has been rated as critical. Affected by this issue is the function update_wp_memory_constants of the file wp-config.php of the component Setting Handler. The manipulation with an unknown input leads to a code injection vulnerability. Using CWE to declare the problem leads to CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The Easy PHP Settings plugin for WordPress is vulnerable to PHP Code Injection in all versions up to, and including, 1.0.4 via the `update_wp_memory_constants()` method. This is due to insufficient input validation on the `wp_memory_limit` and `wp_max_memory_limit` settings before writing them to `wp-config.php`. The `sanitize_text_field()` function used for sanitization does not filter single quotes, allowing an attacker to break out of the string context in a PHP `define()` statement. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject and execute arbitrary PHP code on the server by modifying `wp-config.php`, which is loaded on every page request.

The advisory is available at wordfence.com. This vulnerability is handled as CVE-2026-3352. The exploitation is known to be easy. The attack may be launched remotely. Additional levels of successful authentication are necessary for exploitation. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 03/08/2026). This vulnerability is assigned to T1059 by the MITRE ATT&CK project.
