CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear

The vulnerability allows a remote user to execute arbitrary script in the context of the vulnerable application's domain.

The vulnerability exists due to cross-site scripting in Angular i18n attribute bindings when processing data bindings to untrusted user-generated data on security-sensitive attributes marked with i18n-. A remote user can supply a crafted bound value to execute arbitrary script in the context of the vulnerable application's domain.

User interaction is required, and the issue affects applications that bind unsanitized user input to a vulnerable attribute that is also marked for internationalization.
