CVE-2023-7086Public exploitNetwork attack vector

Stored XSS via unsanitized SVG uploads

Published May 15, 2025 · Updated May 17, 2025

Stored XSS in AblyPeru SVG Uploads Support 2.1.1 and earlier allows remote authenticated users to inject scripts through uploaded SVG files. The plugin accepts SVG media without sanitizing embedded script content and serves the file so its JavaScript executes when accessed. Author-level access is sufficient, and execution requires another user to open the malicious upload or a page that embeds it, enabling browser-context data access and content modification.
