{“lastseen”:””,”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.”,”published”:”2026-06-22T15:41:17.125Z”,”modified”:”2026-06-22T15:46:26.364Z”,”type”:”cve”,”title”:”Angular Service Worker Policy-Bypass \\u0026 Credential-Stripping Vulnerabilities”,”source”:”GitHub_M”,”references”:”https:\/\/github.com\/angular\/angular\/security\/advisories\/GHSA-gv2q-mqqv-365m\\nhttps:\/\/github.com\/angular\/angular\/pull\/67494″,”id”:”CVE-2026-50169″,”bulletinFamily”:””,”cwe”:[“CWE-200″,”CWE-441″,”CWE-524″],”cvelist”:null,”sourceData”:”angular angular \\u003e= 22.0.0-next.0, \\u003c 22.0.0-rc.2\\nangular angular \\u003e= 21.0.0-next.0, \\u003c 21.2.15\\nangular angular \\u003e= 20.0.0-next.0, \\u003c 20.3.22\\nangular angular \\u003e= 19.0.0-next.0, \\u003c 19.2.23\\nangular angular \\u003c= 18.2.14″,”sourceHref”:””,”cvss”:{“score”:5.7,”severity”:”MEDIUM”,”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″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”angular”,”version”:”\\u003e= 22.0.0-next.0, \\u003c 22.0.0-rc.2″,”vendor”:”angular”,”ai_description”:””,”ai_severity”:””,”ai_vendor”:””,”ai_product”:””,”ai_version”:””,”ai_score”:0}<\/p>\n","protected":false},"excerpt":{"rendered":"
