CVE-2026-22610: Angular has XSS Vulnerability via Unsanitized SVG Script Attributes

HighCVSS 8.5 · v4.0—Proof of concept Fix available

Noroxi assessment

Priority: Monitor (action score 34/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.43% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No special conditions are required; it is repeatable.
  • Fixed version: @angular/compiler (npm) 19.2.18, 20.3.16, 21.0.7; @angular/core (npm) 19.2.18, 20.3.16, 21.0.7.

Low priority for now. Upgrade to @angular/compiler (npm) 19.2.18, 20.3.16, 21.0.7; @angular/core (npm) 19.2.18, 20.3.16, 21.0.7 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to versions 19.2.18, 20.3.16, 21.0.7, and 21.1.0-rc.0, a cross-site scripting (XSS) vulnerability has been identified in the Angular Template Compiler. The vulnerability exists because Angular’s internal sanitization schema fails to recognize the href and xlink:href attributes of SVG <script> elements as a Resource URL context. This issue has been patched in versions 19.2.18, 20.3.16, 21.0.7, and 21.1.0-rc.0.
