CVE-2024-6581 Information

Description

A vulnerability in the discussion image upload function of the Lollms application version v9.9 allows for the uploading of SVG files. Due to incomplete filtering in the sanitize_svg function this can lead to cross-site scripting (XSS) vulnerabilities which in turn pose a risk of remote code execution. The sanitize_svg function only removes script elements and ‘on’ event attributes but does not account for other potential vectors for XSS within SVG files. This vulnerability can be exploited when authorized users access a malicious URL containing the crafted SVG file.
