CVE-2025-50182

Ein Angreifer kann mehrere Schwachstellen in IBM InfoSphere Information Server ausnutzen, um beliebigen Programmcode mit Administratorrechten auszuführen, um Informationen offenzulegen, um einen Denial of Service Angriff durchzuführen und um Sicherheitsvorkehrungen zu umgehen.

Ein Angreifer kann mehrere Schwachstellen in IBM Rational Team Concert ausnutzen, um einen Denial-of-Service-Angriff durchzuführen, Eingaben oder Protokolle zu manipulieren, die Authentifizierung zu umgehen, beliebigen Code auszuführen, Cross-Site-Scripting durchzuführen, sensible Informationen offenzulegen oder offene Weiterleitungen auszulösen.

Ein Angreifer kann mehrere Schwachstellen in IBM Business Automation Workflow ausnutzen, um Sicherheitsvorkehrungen zu umgehen, und um einen Denial of Service Angriff durchzuführen.

urllib3 [supports](https://urllib3.readthedocs.io/en/2.4.0/reference/contrib/emscripten.html) being used in a Pyodide runtime utilizing the [JavaScript Fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) or falling back on [XMLHttpRequest](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest). 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. However, the `retries` and `redirect` parameters are ignored with Pyodide; the runtime itself determines redirect behavior. ## Affected usages Any code which relies on urllib3 to control the number of redirects for an HTTP request in a Pyodide runtime. ## Impact Redirects 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. ## Remediation If you use urllib3 in Node.js, upgrade to a patched version of urllib3. Unfortunately, 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.
