CVE-2024-47875Public exploitNetwork attack vector

Cross-site scripting via unbounded DOM nesting

Published Oct 11, 2024 · Updated Nov 3, 2025

Cross-site scripting in DOMPurify before 2.5.0 and 3.0.0 through 3.1.2 allows remote attackers to execute JavaScript via deeply nested HTML. The sanitizer traversal did not track original-tree nesting or node-removal depth, allowing excessive nesting to survive sanitization and mutate into executable markup. Exposure requires an application to sanitize attacker-controlled markup and insert the result into a DOM, where the script runs in that application's origin.
