Check this codebase for CVE-2012-4546 and fix it if it is affected.
What it is: CVE-2012-4546 is a medium-severity vulnerability in Redhat Enterprise Linux, published on 3 Apr 2013. 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-2012-4546 in the wild and no public exploit code.
Affected product: Redhat Enterprise Linux. 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.

What is CVE-2012-4546?
CVE-2012-4546 is a medium-severity vulnerability in Redhat Enterprise Linux, published on 3 Apr 2013. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The default configuration for IPA servers in Red Hat Enterprise Linux 6, when revoking a certificate from an Identity Management replica, does not properly update another Identity Management replica, which causes inconsistent Certificate Revocation Lists (CRLs) to be used and might allow remote attackers to bypass intended access restrictions via a revoked certificate.
