## What is CVE-2022-24757?

CVE-2022-24757 is a high-severity vulnerability in jupyter-server jupyter_server, published on 23 Mar 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The Jupyter Server provides the backend (i.e. the core services, APIs, and REST endpoints) for Jupyter web applications. Prior to version 1.15.4, unauthorized actors can access sensitive information from server logs. Anytime a 5xx error is triggered, the auth cookie and other header values are recorded in Jupyter Server logs by default. Considering these logs do not require root access, an attacker can monitor these logs, steal sensitive auth/cookie information, and gain access to the Jupyter server. Jupyter Server version 1.15.4 contains a patch for this issue. There are currently no known workarounds.

Weakness: CWE-532 (Insertion of Sensitive Information into Log File)

Check this codebase for CVE-2022-24757 and fix it if it is affected.

What it is: CVE-2022-24757 is a high-severity vulnerability in jupyter-server jupyter_server, published on 23 Mar 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2022-24757 in the wild and no public exploit code.

Affected packages and fixed versions:
- jupyter-server (PyPI): affected all versions; fixed in 1.15.4
- jupyter-server (PyPI): affected all versions; fixed in 1.15.4
- jupyter-server (PyPI): affected all versions; fixed in 1.15.4

Task:
1. 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.
2. 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.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
