Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-50169/ (Markdown: https://insights.sbomify.com/CVE-2026-50169/index.md)","id":"CVE-2026-50169","markdown":"https://insights.sbomify.com/CVE-2026-50169/index.md","name":"CVE-2026-50169","record":{"aliases":["DEBIAN-CVE-2026-50169","GHSA-gv2q-mqqv-365m","UBUNTU-CVE-2026-50169"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Angular service worker","requires_auth":"none","summary":"Angular service worker bypasses strict redirect policies, potentially exposing cookies or sensitive data via unintended redirects.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"angular","vendor":"angular"}],"cvss":{"score":5.7,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-524","name":"Use of Cache Containing Sensitive Information"},{"id":"CWE-441","name":"Unintended Proxy or Intermediary"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 22.0.0-rc.2, 21.2.15 20.3.22, and 19.2.23, an issue in the @angular/service-worker package compromises the integrity of request-policy enforcement during request reconstruction. When the Angular Service Worker intercepts network requests for matched assets, it reconstructs a new Request object using an internal helper function. During this reconstruction process, the helper function strips the strict, client-defined request redirect policy configuration (such as redirect: 'error'), falling back to the browser's default 'follow' strategy. If the target web application makes client-side requests with a strict policy (e.g., expecting a network error instead of automatically following redirects), the service worker will bypass this instruction and automatically follow HTTP 3xx redirects to other destinations. This acts as an unintended proxy/intermediary (\"Confused Deputy\") and can result in cookie/credential exposure or same-origin session-restricted data leakage if public dynamic routes redirect to sensitive routes. This vulnerability is fixed in 22.0.0-rc.2, 21.2.15, 20.3.22, and 19.2.23.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Angular Service Worker Policy-Bypass \u0026 Credential-Stripping Vulnerabilities","id":"CVE-2026-50169","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":10,"n_references":2,"next":{"headline":"Angular: Information Leak via Default Caching of Credentialed Requests in HttpTransferCache","id":"CVE-2026-50170"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["18.2.14"],"package":"@angular/service-worker","purl":null,"source":"GHSA-gv2q-mqqv-365m"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["18.2.14"],"package":"@angular/service-worker","purl":"pkg:npm/%40angular/service-worker","source":"GHSA-gv2q-mqqv-365m"},{"ecosystem":"npm","fixed":["19.2.23"],"introduced":["19.0.0-next.0"],"last_affected":[],"package":"@angular/service-worker","purl":null,"source":"GHSA-gv2q-mqqv-365m"},{"ecosystem":"npm","fixed":["19.2.23"],"introduced":["19.0.0-next.0"],"last_affected":[],"package":"@angular/service-worker","purl":"pkg:npm/%40angular/service-worker","source":"GHSA-gv2q-mqqv-365m"},{"ecosystem":"npm","fixed":["20.3.22"],"introduced":["20.0.0-next.0"],"last_affected":[],"package":"@angular/service-worker","purl":null,"source":"GHSA-gv2q-mqqv-365m"},{"ecosystem":"npm","fixed":["20.3.22"],"introduced":["20.0.0-next.0"],"last_affected":[],"package":"@angular/service-worker","purl":"pkg:npm/%40angular/service-worker","source":"GHSA-gv2q-mqqv-365m"},{"ecosystem":"npm","fixed":["21.2.15"],"introduced":["21.0.0-next.0"],"last_affected":[],"package":"@angular/service-worker","purl":null,"source":"GHSA-gv2q-mqqv-365m"},{"ecosystem":"npm","fixed":["21.2.15"],"introduced":["21.0.0-next.0"],"last_affected":[],"package":"@angular/service-worker","purl":"pkg:npm/%40angular/service-worker","source":"GHSA-gv2q-mqqv-365m"},{"ecosystem":"npm","fixed":["22.0.0-rc.2"],"introduced":["22.0.0-next.0"],"last_affected":[],"package":"@angular/service-worker","purl":null,"source":"GHSA-gv2q-mqqv-365m"},{"ecosystem":"npm","fixed":["22.0.0-rc.2"],"introduced":["22.0.0-next.0"],"last_affected":[],"package":"@angular/service-worker","purl":"pkg:npm/%40angular/service-worker","source":"GHSA-gv2q-mqqv-365m"}],"prev":{"headline":"Angular: URL Parser Differential in @angular/platform-server leading to SSRF Allowlist Bypass","id":"CVE-2026-50168"},"products":["angular"],"published":"2026-06-22","related":[{"cvss_score":8.8,"headline":"Angular: Cache-Key Ambiguity in HttpTransferCache Leading to Cross-Request Response Reuse and State Poisoning","id":"CVE-2026-68945","kev_date_added":null,"published":"2026-08-03"},{"cvss_score":8.8,"headline":"Angular: SSRF via Hostname Hijacking in @angular/platform-server","id":"CVE-2026-46417","kev_date_added":null,"published":"2026-06-22"},{"cvss_score":8.8,"headline":"Angular: URL Parser Differential in @angular/platform-server leading to SSRF Allowlist Bypass","id":"CVE-2026-50168","kev_date_added":null,"published":"2026-06-22"},{"cvss_score":8.8,"headline":"Angular: Weak 32-Bit Cache Key Hashing in `HttpTransferCache` Leading to Cross-Request Data Leakage and State Poisoning","id":"CVE-2026-54266","kev_date_added":null,"published":"2026-06-22"},{"cvss_score":8.7,"headline":"Angular: SSRF via protocol-relative and backslash URLs in Angular Platform-Server","id":"CVE-2026-41423","kev_date_added":null,"published":"2026-05-08"},{"cvss_score":8.6,"headline":"Angular: SSRF and Cross-Origin Credential Disclosure via URL Resolution Discrepancy in SSR","id":"CVE-2026-88056","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.6,"headline":"Angular: SSR XSS via Unescaped Processing Instruction (\u003c?...?\u003e) Nodes in Fallback Raw-Content Elements","id":"CVE-2026-88058","kev_date_added":null,"published":"2026-09-10"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-22","vendors":["angular"]},"summary":"Angular service worker bypasses strict redirect policies, potentially exposing cookies or sensitive data via unintended redirects.","url":"https://insights.sbomify.com/CVE-2026-50169/"}
