Jupyter Server open redirect vulnerability

發布日:2020/12/21修改日:2026/5/19

描述

### Impact _What kind of vulnerability is it? Who is impacted?_ Open redirect vulnerability - a maliciously crafted link to a jupyter server could redirect the browser to a different website. All jupyter servers running without a base_url prefix are technically affected, however, these maliciously crafted links can only be reasonably made for known jupyter server hosts. A link to your jupyter server may *appear* safe, but ultimately redirect to a spoofed server on the public internet. This same vulnerability was patched in upstream notebook v5.7.8. ### Patches _Has the problem been patched? What versions should users upgrade to?_ Patched in jupyter_server 1.1.1. If upgrade is not available, a workaround can be to run your server on a url prefix: ``` jupyter server --ServerApp.base_url=/jupyter/ ``` ### References [OWASP page on open redirects](https://cheatsheetseries.owasp.org/cheatsheets/Unvalidated_Redirects_and_Forwards_Cheat_Sheet.html) ### For more information If you have any questions or comments about this advisory, or vulnerabilities to report, please email our security list [[email protected]](mailto:[email protected]).
