GHSA-cvpc-hccg-wmw4
MEDIUMGHSA-cvpc-hccg-wmw4 is a medium-severity (CVSS 6.3) vulnerability in verbb/formie. O3 Security confirms whether GHSA-cvpc-hccg-wmw4 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Formie: Missing authorization in administrative settings allows low-privileged CP users to modify plugin configuration

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
Formie contains a missing authorization vulnerability in administrative settings routes. An authenticated, non-admin Craft CMS control panel user with limited Formie access could directly access Formie settings pages and modify global plugin configuration.
In affected versions, Formie settings-related control panel routes did not consistently enforce the required settings permission on the server side. A low-privileged Craft CMS control panel user with limited Formie access could access /admin/formie/settings, save changes to global plugin settings, and access /admin/formie/settings/import-export.
The issue has been fixed by enforcing the formie-accessSettings permission across Formie settings controllers and related settings actions.
Impact
An authenticated low-privileged CP user may be able to:
- Access Formie administrative settings.
- Modify global Formie plugin configuration.
- Access Formie import/export settings functionality.
This may allow configuration tampering and disruption of form-related workflows. Exploitation requires an authenticated Craft CMS control panel account.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for verbb/formie. 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 verbb/formie to 3.1.28 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-cvpc-hccg-wmw4 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-cvpc-hccg-wmw4 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-cvpc-hccg-wmw4. 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-cvpc-hccg-wmw4 in your dependencies?
O3 detects GHSA-cvpc-hccg-wmw4 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
