ammonia allows stored XSS through unsanitized SVG animate and set attributes
CVE-2026-102342 is fixed in rust-ammonia on 1 platform by DEBIAN-CVE-2026-102342 (version 4.1.4-1), released October 16, 2026. It is not reported as exploited. Patch Radar priority: Routine.
ammonia is a Rust library for repairing and securing untrusted HTML. Prior to 3.3.3, 4.0.3, and 4.1.4, applications that allow the SVG animate or set elements can retain an animation whose attributeName targets href and whose value uses the javascript scheme. The sanitized SVG can therefore create a script-bearing link, and a user who clicks the link can execute attacker-controlled script in the application's origin, enabling stored cross-site scripting. This issue is fixed in versions 3.3.3, 4.0.3, and 4.1.4.
