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.

What is CVE-2022-22967?
CVE-2022-22967 is a high-severity authentication bypass vulnerability in Saltstack Salt, published on 22 Jun 2022. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
An issue was discovered in SaltStack Salt in versions before 3002.9, 3003.5, 3004.2. PAM auth fails to reject locked accounts, which allows a previously authorized user whose account is locked still run Salt commands when their account is locked. This affects both local shell accounts with an active session and salt-api users that authenticate via PAM eauth.
Weakness: CWE-863
