CVE-2026-47730Network attack vector

Cross-site scripting via unescaped profiler names

Published Jul 14, 2026 · Updated Jul 14, 2026

Cross-site scripting in Twig 3.0.0 through 3.25.0 allows attackers to inject HTML into browser-rendered profiler dumps. Twig\Profiler\Dumper\HtmlDumper inserts Profile::getTemplate() and Profile::getName() values into markup without HTML encoding. Exploitation requires attacker control of a loader-supplied template or profile name and a user to render the generated profiler output in a browser, enabling script execution in that browser context.
