Cross-Site Scripting Vulnerability in Angular Development Platform

CVE-2026-22610

What is CVE-2026-22610?

CVE-2026-22610 describes a cross-site scripting (XSS) vulnerability in the Angular development platform, which is widely utilized for building robust mobile and desktop web applications using TypeScript, JavaScript, and other programming languages. The vulnerability arises from the Angular Template Compiler, where its internal sanitization schema fails to properly recognize the href and xlink:href attributes of SVG <script> elements as a resource URL context. This oversight can potentially allow attackers to inject malicious scripts into web applications, which could compromise user data and the integrity of the application. The issue has been addressed in recent releases, specifically in versions 19.2.18, 20.3.16, 21.0.7, and 21.1.0-rc.0, making it crucial for organizations relying on Angular to upgrade to these patched versions to safeguard against potential exploitation.

Potential impact of CVE-2026-22610

1. Data Breaches: The XSS vulnerability may allow unauthorized actors to execute scripts in the context of users’ sessions, potentially exposing sensitive data such as user credentials and personal information to attackers.

2. Malware Injection: Attackers can leverage this vulnerability to inject malicious scripts, leading to unauthorized actions being carried out on behalf of users or the installation of malware on their devices.

3. Reputation Damage: Exploitation of this vulnerability could significantly damage the reputation of organizations using Angular, leading to a loss of user trust and potential financial repercussions resulting from security incidents and data breaches.
