Check this codebase for CVE-2017-12173 and fix it if it is affected.
What it is: CVE-2017-12173 is a medium-severity vulnerability in Redhat Enterprise Linux Desktop, published on 27 Jul 2018. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2017-12173 in the wild and no public exploit code.
Affected product: Redhat Enterprise Linux Desktop. 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-2017-12173?
CVE-2017-12173 is a medium-severity vulnerability in Redhat Enterprise Linux Desktop, published on 27 Jul 2018. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
It was found that sssd's sysdb_search_user_by_upn_res() function before 1.16.0 did not sanitize requests when querying its local cache and was vulnerable to injection. In a centralized login environment, if a password hash was locally cached for a given user, an authenticated attacker could use this flaw to retrieve it.
