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":"2025-12-01T22:35:59.211+00:00","modifiedAt":"2026-06-02T13:00:31.963+00:00","affected":[{"ecosystem":"Vendor product","name":"angular","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"angular\",\n                    \"product\": \"angular\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 21.0.0-next.0 < 21.0.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 20.0.0-next.0 < 20.3.15\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 19.0.0-next.0 < 19.2.17\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"<= 18.2.14\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","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","score":8.5,"severity":"HIGH"}],"references":["https://github.com/angular/angular/security/advisories/GHSA-v4hv-rgfq-gp49","https://github.com/angular/angular/commit/1c6b0704fb63d051fab8acff84d076abfbc4893a"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-66412","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-66412","identifiers":["CVE-2025-66412"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
