Description
List of key / value pairs assigned to OptionsetField or CheckboxSetField do not have a default casting assigned to them. The effect of this is a potential XSS vulnerability in lists where either key or value contain unescaped HTML.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for silverstripe/framework. 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 silverstripe/framework to 3.1.20 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-468j-6jrc-2rjx 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-468j-6jrc-2rjx 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-468j-6jrc-2rjx. 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-468j-6jrc-2rjx in your dependencies?
O3 detects GHSA-468j-6jrc-2rjx across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
