## What is GHSA-cc2j-92jq-wgjg?

GHSA-cc2j-92jq-wgjg is a vulnerability in ezsystems/ezpublish-legacy, published on 15 May 2024. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

This security advisory fixes an information disclosure vulnerability in the legacy admin content tree menu. If a view has been disabled in site.ini [SiteAccessRules] Rules, and an attacker accesses the backend with the URL to this module, then the tree menu may be displayed. Since the tree menu may contain hidden items, this may lead to information disclosure. We recommend that you install this Security Update as soon as possible.

To install, use Composer to update to one of the "Resolving versions" mentioned above, or apply this patch manually: https://github.com/ezsystems/ezpublish-legacy/commit/a4a0470f8d80f012fe14e4f8ab11c7d14375986c

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.
