This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
This security advisory fixes a vulnerability in eZ Platform, and we recommend that you install it as soon as possible. The issue is that the REST API may be made to disclose the names of all available site accesses. The severity of this depends on your installation, please consider your response accordingly.
To install, use Composer to update "ezsystems/ezpublish-kernel" to one of the "Resolving versions" mentioned above, or apply this patch manually: https://github.com/ezsystems/ezpublish-kernel/commit/1551723ec134878a4cb598bfc5d900ba6164117a

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ezsystems/ezpublish-kernel. 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-kernel to 7.3.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9wwx-c723-vm8x 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-9wwx-c723-vm8x 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-9wwx-c723-vm8x. 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-9wwx-c723-vm8x in your dependencies?
O3 detects GHSA-9wwx-c723-vm8x across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
