Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVE-2026-32635

High
8.6/10

Summary

A Cross-Site Scripting (XSS) vulnerability has been identified in the Angular runtime and compiler. It occurs when the application uses a security-sensitive attribute (for example href on an anchor tag) together with Angular's ability to internationalize attributes. Enabling internationalization for the sensitive attribute by adding `i18n-<attribute>` name bypasses Angular's built-in sanitization mechanism, which when combined with a data binding to untrusted user-generated data can allow an attacker to inject a malicious script. When exploited, this vulnerability allows an attacker to execute arbitrary code within the context of the vulnerable application's domain. Affected are versions 17.0.0.next.0 prior to 19.2.20, 20.0.0-next.0.0.0 prior to 20.3.18, 21.0.0-next.0 prior to 21.2.4 and 22.0.0-next.0 prior to 22.0.0-next.3.

CWE-79 - Cross Site Scripting

Cross-Site Scripting, commonly referred to as XSS, is the most dominant class of vulnerabilities. It allows an attacker to inject malicious code into a pregnable web application and victimize its users. The exploitation of such a weakness can cause severe issues such as account takeover, and sensitive data exfiltration. Because of the prevalence of XSS vulnerabilities and their high rate of exploitation, it has remained in the OWASP top 10 vulnerabilities for years.
