MEDIUMeZ Platform Admin UI vulnerable to DOM-based Cross-site Scripting in file upload widget
Blast Radius
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
Impact
The file upload widget is vulnerable to XSS payloads in filenames. Access permission to upload files is required. As such, in most cases only authenticated editors and administrators will have the required permission. It is not persistent, i.e. the payload is only executed during the upload. In effect, an attacker will have to trick an editor/administrator into uploading a strangely named file. The fix ensures XSS is escaped.
Patches
See "Patched versions". Commit: https://github.com/ezsystems/ezplatform-admin-ui/commit/7a9f991b200fa5a03d49cd07f50577c8bc90a30b
Workarounds
None.

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. 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/ezplatform-admin-ui to 3.3.39 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gc5h-6jx9-q2qh 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-gc5h-6jx9-q2qh 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-gc5h-6jx9-q2qh. 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-gc5h-6jx9-q2qh in your dependencies?
O3 detects GHSA-gc5h-6jx9-q2qh across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
