Prior to 21.0.2, 20.3.15, and 19.2.17, A Stored Cross-Site Scripting (XSS) vulnerability has been identified in the Angular Template Compiler. It occurs because the compiler's internal security schema is incomplete, allowing attackers to bypass Angular's built-in security sanitization. Specifically, the schema fails to classify certain URL-holding attributes (e.g., those that could contain javascript: URLs) as requiring strict URL security, enabling the injection of malicious scripts. This vulnerability is fixed in 21.0.2, 20.3.15, and 19.2.17.","state":0,"publishedAt":"2025-12-01T23:15:53.89+00:00","modifiedAt":"2026-10-18T18:10:00.1+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":8.5,"severity":"HIGH"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/angular/angular/commit/1c6b0704fb63d051fab8acff84d076abfbc4893a","https://github.com/angular/angular/security/advisories/GHSA-v4hv-rgfq-gp49","https://cert-portal.siemens.com/productcert/html/ssa-253495.html","https://cert-portal.siemens.com/productcert/html/ssa-485750.html"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-66412","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Modified","weaknesses":["CWE-79"],"productCriteria":["cpe:2.3:a:angular:angular:*:*:*:*:*:node.js:*:*"],"sourceDates":{"published":"2025-12-01T23:15:53.890","lastModified":"2026-10-18T18:10:00.100"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
