XSS in richtext custom tag attributes in ezsystems/ezplatform-richtext
Real-World Exposure
ezsystems/ezplatform-richtextReal-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
The rich text editor does not escape attribute data when previewing custom tags. This means XSS is possible if custom tags are used, for users who have access to editing rich text content. Frontend content view is not affected, but the vulnerability could be used by editors to attack other editors. The fix ensures custom tag attribute data is escaped in the editor.
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ezsystems/ezplatform-richtext, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update ezsystems/ezplatform-richtext to 2.3.7.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-fxwm-rx68-p5vx 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-fxwm-rx68-p5vx can be triaged on real exposure rather than presence alone.
Tailored to GHSA-fxwm-rx68-p5vx. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
