CVE-2025-2542:
WordPress vulnerability analysis and mitigation

Overview

The Your Simple SVG Support plugin for WordPress contains a Stored Cross-Site Scripting (XSS) vulnerability in versions up to and including 1.0.1. The vulnerability was discovered and disclosed on March 25, 2025, and is tracked as CVE-2025-2542. The issue affects the SVG file upload functionality in the plugin, which is used to enable SVG image support in WordPress installations (NVD).

Technical details

The vulnerability stems from insufficient input sanitization and output escaping when handling SVG file uploads. This security flaw exists in the plugin's file processing functionality, allowing authenticated users with Author-level privileges or higher to inject malicious web scripts through SVG files. The vulnerability has been assigned a CVSS v3.1 base score of 6.4 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N, indicating a network-accessible vulnerability with low attack complexity requiring low privileges (Wordfence).

Impact

When exploited, this vulnerability allows attackers to inject arbitrary web scripts that execute whenever a user accesses the compromised SVG file. This can lead to the execution of malicious JavaScript code in the context of other users' browsers who view the affected pages, potentially compromising user data and website functionality (NVD).

Mitigation and workarounds

A security update has been released in version 1.0.2 of the Your Simple SVG Support plugin. Users are strongly advised to update to this latest version to address the vulnerability. The update implements improved input sanitization and output escaping mechanisms (WordPress Plugin).
