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

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ezsystems/ezpublish-legacy. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update ezsystems/ezpublish-legacy to 2017.8.1.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-cc2j-92jq-wgjg is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-cc2j-92jq-wgjg is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-cc2j-92jq-wgjg. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-cc2j-92jq-wgjg in your dependencies?
O3 detects GHSA-cc2j-92jq-wgjg across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
