This means you can use Python libraries to make HTTP requests from your browser or Node.js. Additionally, urllib3 provides [a mechanism](https://urllib3.readthedocs.io/en/2.4.0/user-guide.html#retrying-requests) to control redirects.\n\nHowever, the `retries` and `redirect` parameters are ignored with Pyodide; the runtime itself determines redirect behavior.\n\n\n## Affected usages\n\nAny code which relies on urllib3 to control the number of redirects for an HTTP request in a Pyodide runtime.\n\n\n## Impact\n\nRedirects are often used to exploit SSRF vulnerabilities. An application attempting to mitigate SSRF or open redirect vulnerabilities by disabling redirects may remain vulnerable if a Pyodide runtime redirect mechanism is unsuitable.\n\n\n## Remediation\n\nIf you use urllib3 in Node.js, upgrade to a patched version of urllib3.\n\nUnfortunately, browsers provide no suitable way which urllib3 can use: `XMLHttpRequest` provides no control over redirects, the Fetch API returns `opaqueredirect` responses lacking data when redirects are controlled manually. Expect default browser behavior for redirects.", "aliases": [ { "alias": "CVE-2025-50182" }, { "alias": "GHSA-48p4-8xcf-vxj5" } ], "fixed_packages": [ { "url":
