Overview

The Custom Field Suite plugin for WordPress contains a Stored Cross-Site Scripting vulnerability (CVE-2024-3558) affecting versions up to and including 2.6.7. The vulnerability was discovered in the 'cfs[post_title]' parameter due to insufficient input sanitization and output escaping (NVD).

Technical details

The vulnerability exists due to improper neutralization of input during web page generation, classified as CWE-79. The CVSS v3.1 base score is 5.4 (Medium) according to NVD's assessment, while Wordfence rates it at 6.4 (Medium). The vulnerability affects the plugin's handling of the 'cfs[post_title]' parameter, where insufficient input sanitization and output escaping allows for script injection (NVD, Wordfence).

Impact

Mitigation and workarounds
