The wp-svg-upload WordPress plugin through version 1.0.0 contains a stored Cross-Site Scripting (XSS) vulnerability. The vulnerability was discovered on March 5, 2025, and was assigned CVE-2024-11847. The issue affects the wp-svg-upload plugin and impacts WordPress installations using this plugin (WPScan).

The vulnerability stems from the plugin's failure to properly sanitize SVG file contents. The issue has been assigned a CVSS v3.1 base score of 4.8 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N. The vulnerability is classified under CWE-79 (Cross-Site Scripting) (NVD).

When exploited, this vulnerability allows users with author-level privileges or higher to upload SVG files containing malicious JavaScript code, which can then be used to conduct stored XSS attacks. When other users browse to the URL of the uploaded SVG file, the malicious JavaScript code is executed in their browser context (WPScan).

The vulnerability can be exploited by uploading an SVG file containing malicious JavaScript code. A proof of concept demonstrates that an author can upload an SVG file containing simple JavaScript code such as alert('xss'), which will execute when users access the uploaded file's URL (WPScan).

Currently, there is no known fix available for this vulnerability in the wp-svg-upload plugin (WPScan).
