Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2025-6997 impacting themerex addons. Evaluated with CVSS Base Score of 6.4 (MEDIUM).

Original NVD Description

Source: NIST NVD
The ThemeREX Addons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 2.35.1.1 due to insufficient input sanitization and output escaping. The pluginโ€™s SVG rendering routine calls the trx_addons_get_svg_from_file() function on an unvalidated 'svg' parameter supplied via the shortcode or Elementor widget settings, then outputs it via the trx_addons_show_layout() function. Because there is no check on the URLโ€™s origin, scheme, or the SVG content itself, authenticated attackers, with Contributor-level access and above, can supply a remote SVG and inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.
