Description
Impact
This security advisory resolves an XSS vulnerability in acronym custom tag in Rich Text, 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 ibexa/fieldtype-richtext. 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 ibexa/fieldtype-richtext to 5.0.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8c2g-f8jm-5cr7 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-8c2g-f8jm-5cr7 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-8c2g-f8jm-5cr7. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
