## What is CVE-2010-0014?

CVE-2010-0014 is a low-severity authentication bypass vulnerability in n/a, published on 14 Jan 2010. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

System Security Services Daemon (SSSD) before 1.0.1, when the krb5 auth_provider is configured but the KDC is unreachable, allows physically proximate attackers to authenticate, via an arbitrary password, to the screen-locking program on a workstation that has any user's Kerberos ticket-granting ticket (TGT); and might allow remote attackers to bypass intended access restrictions via vectors involving an arbitrary password in conjunction with a valid TGT.

Weakness: CWE-287 (Improper Authentication)

Check this codebase for CVE-2010-0014 and fix it if it is affected.

What it is: CVE-2010-0014 is a low-severity authentication bypass vulnerability in n/a, published on 14 Jan 2010. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2010-0014 in the wild and no public exploit code.

Affected product: n/a. 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.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
