This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
When editing a user, group or any object in the Syncope Console, HTML tags could be added to any text field and could lead to potential exploits. The same vulnerability was found in the Syncope Enduser, when editing “Personal Information” or “User Requests”.
Users are recommended to upgrade to version 3.0.8, which fixes this issue.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.syncope.client.idrepo:syncope-client-idrepo-common-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 org.apache.syncope.client.idrepo:syncope-client-idrepo-common-ui to 3.0.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-38503 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 CVE-2024-38503 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 CVE-2024-38503. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
