Stored XSS via unsanitized SVG uploads
Published Nov 16, 2022 · Updated Feb 7, 2025
Stored cross-site scripting in SVG Support 2.5 and 2.5.1 allows remote authenticated users to execute JavaScript via SVG uploads. The upload path accepts SVG content while sanitization is disabled by default and does not limit uploads to administrators, allowing embedded scripts to persist in posts, pages, or image URLs. Author-level access is required, and visiting the rendered content executes attacker-controlled code in the browser.
