Silverstripe XSS in TreeDropdownField and TreeMultiSelectField
Real-World Exposure
silverstripe/frameworkReal-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
A cross-site scripting vulnerability has been discovered in the TreeDropdownField and TreeMultiSelectField.
This vulnerability can only be exploited if a user with CMS access has posted malicious or unescaped HTML into any of the dataobjects used as a data source for either of these fields.
This has been resolved by ensuring that all dataobjects used as a data source have their content safely encoded.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for silverstripe/framework, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update silverstripe/framework to 3.1.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r32j-mr8p-hfp8 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-r32j-mr8p-hfp8 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-r32j-mr8p-hfp8. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
