Prior to 20.3.34 and 21.0.3, the @angular/common HttpClient function xsrfInterceptorFn uses a regular expression that does not normalize request URLs in the same way as the browser's WHATWG URL parser. With XSRF protection enabled, a mutating HTTP request to an attacker-controlled URL containing backslashes, stripped control characters or spaces, or removable ASCII whitespace can be misclassified as relative and same-origin, causing the interceptor to attach the X-XSRF-TOKEN header before the browser dispatches the request to a cross-origin host. With permissive CORS handling for the custom header, the attacker can obtain the victim's XSRF token and use it to perform cross-site request forgery against the victim session. This issue is fixed in versions 20.3.34 and 21.0.3.","state":0,"publishedAt":"2026-11-05T20:25:07.322+00:00","modifiedAt":"2026-11-05T20:25:07.322+00:00","affected":[{"ecosystem":"Vendor product","name":"angular","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"angular\",\n                    \"product\": \"angular\",\n                    \"versions\": [\n                        {\n                            \"version\": \"<= 19.2.25\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 20.0.0, < 20.3.34\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 21.0.0, < 21.0.3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":5.9,"severity":"MEDIUM"}],"references":["https://github.com/angular/angular/security/advisories/GHSA-jfgx-762w-99vr","https://github.com/angular/angular/issues/71294","https://github.com/angular/angular/pull/65683","https://github.com/angular/angular/pull/71295","https://github.com/angular/angular/commit/20474d3f0fd7c64071add6e84acf720627e5c19b","https://github.com/angular/angular/commit/933ce817d53e25926844fa56af8230816763d08e","https://github.com/angular/angular/releases/tag/21.0.3","https://github.com/angular/angular/releases/tag/v20.3.34"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-111753","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-111753","identifiers":["CVE-2026-111753"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
