CVE-2026-22610Network attack vector

Cross-site scripting via unsanitized SVG script URLs

Published Jan 10, 2026 · Updated Jan 10, 2026

Cross-site scripting in the Angular Template Compiler before 19.2.18, 20.3.16, 21.0.7, and 21.1.0-rc.0 allows attackers to execute script. The DOM security schema omits href and xlink:href on SVG script elements from the Resource URL context, so getUrlSanitizer applies ordinary URL sanitization to attacker-controlled bindings. Exploitation requires an application template with an SVG script element, a bound affected attribute, and untrusted bound data; successful exploitation runs script in an active user's browser.
