Prior to 20.3.33, 21.2.25, and 22.2.1, ServerPlatformLocation in Angular server-side rendering checks for protocol-relative URLs before WHATWG URL normalization. A request path containing a popping dot segment followed by multiple slashes can bypass the raw resolveUrl check and normalize to a pathname beginning with two slashes. When Angular SSR detects a mismatch with the router's final location, it can place that pathname in an HTTP Location header, causing a browser to navigate to an attacker-controlled origin. Affected applications use @angular/platform-server and @angular/ssr and either expose compatible parameter or child route shapes or pass user-controlled navigation targets through infrastructure that preserves the relevant dot segments or semicolons. Pure client-side SPAs are not affected. This issue is fixed in versions 20.3.33, 21.2.25, and 22.2.1."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"angular","product":"angular","versions":[{"version":"<= 19.2.25","status":"affected"},{"version":">= 20.0.0, < 20.3.33","status":"affected"},{"version":">= 21.0.0, < 21.2.25","status":"affected"},{"version":">= 22.0.0, < 22.2.1","status":"affected"}]}]}],"metrics":{"cvssMetricV40":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"4.0","vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/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","baseScore":5.1,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"NONE","userInteraction":"ACTIVE","vulnConfidentialityImpact":"NONE","vulnIntegrityImpact":"NONE","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"LOW","subIntegrityImpact":"LOW","subAvailabilityImpact":"NONE","exploitMaturity":"NOT_DEFINED","confidentialityRequirement":"NOT_DEFINED","integrityRequirement":"NOT_DEFINED","availabilityRequirement":"NOT_DEFINED","modifiedAttackVector":"NOT_DEFINED","modifiedAttackComplexity":"NOT_DEFINED","modifiedAttackRequirements":"NOT_DEFINED","modifiedPrivilegesRequired":"NOT_DEFINED","modifiedUserInteraction":"NOT_DEFINED","modifiedVulnConfidentialityImpact":"NOT_DEFINED","modifiedVulnIntegrityImpact":"NOT_DEFINED","modifiedVulnAvailabilityImpact":"NOT_DEFINED","modifiedSubConfidentialityImpact":"NOT_DEFINED","modifiedSubIntegrityImpact":"NOT_DEFINED","modifiedSubAvailabilityImpact":"NOT_DEFINED","Safety":"NOT_DEFINED","Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","valueDensity":"NOT_DEFINED","vulnerabilityResponseEffort":"NOT_DEFINED","providerUrgency":"NOT_DEFINED"}}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-11-03T21:23:29.234599Z","id":"CVE-2026-111754","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-601"}]}],"references":[{"url":"https://github.com/angular/angular/commit/450af9c813c7660b9bd91e5635f705ee3ed7b32a","source":"security-advisories@github.com"},{"url":"https://github.com/angular/angular/commit/83944fc8c50e86be90e8ec4184cd15002b5af262","source":"security-advisories@github.com"},{"url":"https://github.com/angular/angular/commit/928dcfd2582152655b5559509d057bf6a5a19521","source":"security-advisories@github.com"},{"url":"https://github.com/angular/angular/issues/71076","source":"security-advisories@github.com"},{"url":"https://github.com/angular/angular/pull/71077","source":"security-advisories@github.com"},{"url":"https://github.com/angular/angular/pull/71078","source":"security-advisories@github.com"},{"url":"https://github.com/angular/angular/pull/71079","source":"security-advisories@github.com"},{"url":"https://github.com/angular/angular/releases/tag/v20.3.33","source":"security-advisories@github.com"},{"url":"https://github.com/angular/angular/releases/tag/v21.2.25","source":"security-advisories@github.com"},{"url":"https://github.com/angular/angular/releases/tag/v22.2.1","source":"security-advisories@github.com"},{"url":"https://github.com/angular/angular/security/advisories/GHSA-w739-gvwx-grc3","source":"security-advisories@github.com"}]}
