## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2014-0764 and fix it if it is affected.

What it is: CVE-2014-0764 is a high-severity memory corruption vulnerability in Advantech WebAccess, published on 12 Apr 2014. It can be exploited over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2014-0764 in the wild and no public exploit code.

Affected product: Advantech WebAccess. 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.
