Real-World Exposure
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
This security advisory resolves an XSS vulnerability in image asset names, content language names and future publishing in the back office of the DXP. Back office access and varying levels of editing and management permissions are required to exploit this vulnerability. This typically means Editor or Administrator role, or similar. Injected XSS is persistent and may in some cases be reflected in the front office, possibly affecting end users. The fixes ensure XSS is escaped, and any existing injected XSS is rendered harmless.
Patches
See "Patched versions".
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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update ezsystems/ezplatform-admin-ui to 2.3.39 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-99c7-c3mw-mxhv 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-99c7-c3mw-mxhv can be triaged on real exposure rather than presence alone.
Tailored to GHSA-99c7-c3mw-mxhv. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
