CVE-2025-2543
CVE-2025-2543 — Advanced Accordion Gutenberg Block <= 5.0.2 - Authenticated (Author+) Stored Cross-Site Scripting via SVG File Upload
The Advanced Accordion Gutenberg Block plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 5.0.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.
