Real-World Exposure
verbb/formieReal-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
Impact
When importing a form from JSON, if the field label or handle contained malicious content, the output wasn't correctly escaped when viewing a preview of what was to be imported.
As imports are undertaking primarily by users who have themselves exported the form from one environment to another, and would require direct manipulation of the JSON export, this is marked as moderate. This vulnerability will not occur unless someone deliberately tampers with the export.
Patches
This has been fixed in Formie 2.1.44. Users should ensure they are running at least this version.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for verbb/formie, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update verbb/formie to 2.1.44 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-p9hh-mh5x-wvx3 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-p9hh-mh5x-wvx3 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-p9hh-mh5x-wvx3. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
