## What is CVE-2023-46138?

CVE-2023-46138 is a low-severity vulnerability in jumpserver, published on 30 Oct 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

JumpServer is an open source bastion host and maintenance security audit system that complies with 4A specifications. Prior to version 3.8.0, the default email for initial user admin is `admin[@]mycompany[.]com`, and users reset their passwords by sending an email. Currently, the domain `mycompany.com` has not been registered. However, if it is registered in the future, it may affect the password reset functionality. This issue has been patched in version 3.8.0 by changing the default email domain to `example.com`. Those who cannot upgrade may change the default email domain to `example.com` manually.

Weakness: CWE-640 (Weak Password Recovery Mechanism for Forgotten Password)

What it is: CVE-2023-46138 is a low-severity vulnerability in jumpserver, published on 30 Oct 2023. 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-2023-46138 in the wild and no public exploit code.

Affected product: jumpserver. No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
