eZ Platform Admin UI Cross-site Scripting vulnerability
Real-World Exposure
ezsystems/ezplatform-admin-ui🐘ezsystems/ezplatform-admin-uiReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
This security advisory fixes a severe vulnerability in the eZ Platform Admin UI, and we recommend that you install it as soon as possible. Parts of the Admin UI are vulnerable to XSS injection. All 2.x sites are at risk, and particularly those that allow user generated content. The update adds the necessary escaping of injected code. This resolves the issue both for code that has already been injected, and any future such code.
To install, use Composer to update "ezsystems/ezplatform-admin-ui" and "ezsystems/ezplatform-page-builder" to one of the "Resolving versions" mentioned above. (ezplatform-page-builder exists only in eZ Platform Enterprise Edition.)

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ezsystems/ezplatform-admin-ui, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update ezsystems/ezplatform-admin-ui to 1.3.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-q73v-79x3-jv2w 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-q73v-79x3-jv2w can be triaged on real exposure rather than presence alone.
Tailored to GHSA-q73v-79x3-jv2w. 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-q73v-79x3-jv2w in your dependencies?
O3 Security finds GHSA-q73v-79x3-jv2w across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
