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 GHSA-xmp3-7745-g4vj?

Official description
This Security Advisory is about a vulnerability in ezsystems/ez-support-tools v2.2, part of Ibexa DXP v3.2. Older versions are not affected. A user having insufficient permissions is able to access the system information tabs if they type in the direct link (the link is not shown in the menu). The "Setup / System info" policy should be required to access it, but only backend login is actually required. This means any editor can see core system information, including the output from phpinfo(). The fix ensures that the access policy is correctly verified.
