Answer in brief
CVE-2026-102342 records a Medium severity (CVSS 5.4) vulnerability in ammonia allows stored XSS through unsanitized SVG animate and set attributes. The current sources do not mark it as known exploited. The current feed maps ammonia (crates.io), ammonia (crates.io), ammonia (crates.io), ammonia (crates.io) and additional mapped packages. Check affected ranges and fixed versions before updating.

HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 5.4. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
