The vulnerability exists because Angular’s internal URL reconstruction logic directly trusts and consumes user-controlled HTTP headers specifically the Host and `X-Forwarded-*` family to determine the application's base origin without any validation of the destination domain.\n\nSpecifically, the framework didn't have checks for the following:\n- **Host Domain**: The `Host` and `X-Forwarded-Host` headers were not checked to belong to a trusted origin. This allows an attacker to redefine the \"base\" of the application to an arbitrary external domain.\n- **Path & Character Sanitization**: The `X-Forwarded-Host` header was not checked for path segments or special characters, allowing manipulation of the base path for all resolved relative URLs.\n- **Port Validation**: The `X-Forwarded-Port` header was not verified as numeric, leading to malformed URI construction or injection attacks.\n\n\nThis vulnerability manifests in two primary ways:\n\n- **Implicit Relative URL Resolution**: Angular's `HttpClient` resolves relative URLs against this unvalidated and potentially malformed base origin. An attacker can \"steer\" these requests to an external server or internal service.\n- **Explicit Manual Construction**: Developers injecting the `REQUEST` object to manually construct URLs (for fetch or third-party SDKs) directly inherit these unsanitized values. By accessing the `Host` / `X-Forwarded-*` headers, the application logic may perform requests to attacker-controlled destinations or malformed endpoints.","references":[{"reference_url":"https://angular.dev/best-practices/security#preventing-server-side-request-forgery-ssrf","reference_id":"","reference_type":"","scores":[{"value":"9.2","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:H/SI:L/SA:N"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:Y/T:P/P:M/B:A/M:M/D:T/2026-02-27T17:59:01Z/"}],"url":"https://angular.dev/best-practices/security#preventing-server-side-request-forgery-ssrf"},{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-27739","reference_id":"","reference_type":"","scores":[{"value":"0.00061","scoring_system":"epss","scoring_elements":"0.19416","published_at":"2026-06-07T12:55:00Z"},{"value":"0.00061","scoring_system":"epss","scoring_elements":"0.19459","published_at":"2026-06-06T12:55:00Z"},{"value":"0.00061","scoring_system":"epss","scoring_elements":"0.19466","published_at":"2026-06-05T12:55:00Z"},{"value":"0.00061","scoring_system":"epss","scoring_elements":"0.19346","published_at":"2026-06-08T12:55:00Z"},{"value":"0.00061","scoring_system":"epss","scoring_elements":"0.19371","published_at":"2026-06-09T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-27739"},{"reference_url":"https://developer.mozilla.org/en-US/docs/Web/Security/Attacks/SSRF","reference_id":"","reference_type":"","scores":[{"value":"9.2","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:H/SI:L/SA:N"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:Y/T:P/P:M/B:A/M:M/D:T/2026-02-27T17:59:01Z/"}],"url":"https://developer.mozilla.org/en-US/docs/Web/Security/Attacks/SSRF"},{"reference_url":"https://github.com/angular/angular-cli","reference_id":"","reference_type":"","scores":[{"value":"9.2","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:H/SI:L/SA:N"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/angular/angular-cli"},{"reference_url":"https://github.com/angular/angular-cli/pull/32516","reference_id":"","reference_type":"","scores":[{"value":"9.2","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:H/SI:L/SA:N"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:Y/T:P/P:M/B:A/M:M/D:T/2026-02-27T17:59:01Z/"}],"url":"https://github.com/angular/angular-cli/pull/32516"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27739","reference_id":"CVE-2026-27739","reference_type":"","scores":[{"value":"9.2","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:H/SI:L/SA:N"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27739"},{"reference_url":"https://github.com/advisories/GHSA-x288-3778-4hhx","reference_id":"GHSA-x288-3778-4hhx","reference_type":"","scores":[{"value":"CRITICAL","scoring_system":"cvssv3.1_qr","scoring_elements":""}],"url":"https://github.com/advisories/GHSA-x288-3778-4hhx"},{"reference_url":"https://github.com/angular/angular-cli/security/advisories/GHSA-x288-3778-4hhx","reference_id":"GHSA-x288-3778-4hhx","reference_type":"","scores":[{"value":"CRITICAL","scoring_system":"cvssv3.1_qr","scoring_elements":""},{"value":"9.2","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:H/SI:L/SA:N"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:Y/T:P/P:M/B:A/M:M/D:T/2026-02-27T17:59:01Z/"}],"url":"https://github.com/angular/angular-cli/security/advisories/GHSA-x288-3778-4hhx"}],"fixed_packages":[],"aliases":["CVE-2026-27739","GHSA-x288-3778-4hhx"],"risk_score":4.5,"exploitability":"0.5","weighted_severity":"9.0","resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-c849-wwtp-vkhz"}],"fixing_vulnerabilities":[],"risk_score":"4.5","resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540nguniversal/common@5.0.0-beta.6"}
