## What is CVE-2022-43928?

CVE-2022-43928 is a medium-severity vulnerability in IBM Db2 Mirror for i, published on 7 Apr 2023. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

The IBM Toolbox for Java (Db2 Mirror for i 7.4 and 7.5) could allow a user to obtain sensitive information, caused by utilizing a Java string for processing. Since Java strings are immutable, their contents exist in memory until garbage collected.  This means sensitive data could be visible in memory over an indefinite amount of time. IBM has addressed this issue by reducing the amount of time the sensitive data is visible in memory.  IBM X-Force ID:  241675.

Check this codebase for CVE-2022-43928 and fix it if it is affected.

What it is: CVE-2022-43928 is a medium-severity vulnerability in IBM Db2 Mirror for i, published on 7 Apr 2023. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2022-43928 in the wild and no public exploit code.

Affected product: IBM Db2 Mirror for i. 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.
