Check this codebase for CVE-2022-34169 and fix it if it is affected.
What it is: CVE-2022-34169 is a high-severity vulnerability in Debian Debian Linux, published on 19 Jul 2022. 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-2022-34169 in the wild and no public exploit code.
Affected packages and fixed versions:
- xalan:xalan (Maven): affected all versions; fixed in 2.7.3
- xalan:xalan (Maven): affected all versions; fixed in 2.7.3
- java (Bitnami): affected from 1.8.0-333 up to 1.8.0-333; no fix listed
- java-min (Bitnami): affected from 1.8.0-333 up to 1.8.0-333; no fix listed
- jre (Bitnami): affected from 1.8.0-333 up to 1.8.0-333; no fix listed
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.

Official description
The Apache Xalan Java XSLT library is vulnerable to an integer truncation issue when processing malicious XSLT stylesheets. This can be used to corrupt Java class files generated by the internal XSLTC compiler and execute arbitrary Java bytecode. Users are recommended to update to version 2.7.3 or later. Note: Java runtimes (such as OpenJDK) include repackaged copies of Xalan.
Weakness: CWE-681
