LOWStatamic CMS's incorrect authorization lets view-only users submit Live Preview content reserved for editors
Blast Radius
statamic/cms🐘statamic/cmsReal-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
The Live Preview endpoint for existing entries and terms only checked view authorization, but it accepts and renders caller-supplied field values. A Control Panel user with view but not edit permission could therefore submit content they were not authorized to author and generate a shareable Live Preview URL rendering it.
Patches
This has been fixed in 5.74.0 and 6.20.3.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | statamic/cms | all versions | 5.74.0 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for statamic/cms. 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 statamic/cms to 5.74.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7mqq-4v55-88gh 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-7mqq-4v55-88gh 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-7mqq-4v55-88gh. 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-7mqq-4v55-88gh in your dependencies?
O3 detects GHSA-7mqq-4v55-88gh across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
