GHSA-cg8j-8w52-735v
CRITICALGHSA-cg8j-8w52-735v is a critical-severity (CVSS 9.8) vulnerability in silverstripe/cms. O3 Security confirms whether GHSA-cg8j-8w52-735v is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Missing warning can lead to unauthenticated admin access in SilverStripe
Real-World Exposure
silverstripe/cms🐘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
In SilverStripe through 4.3.3, a missing warning about leaving install.php in a public webroot can lead to unauthenticated admin access.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | silverstripe/cms | ≥ 4.4.0&&< 4.4.4 | 4.4.4 |
| 🐘Packagist | silverstripe/framework | ≥ 4.1.0&&< 4.3.5 | 4.3.5 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for silverstripe/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 silverstripe/cms to 4.4.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-cg8j-8w52-735v 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-cg8j-8w52-735v 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-cg8j-8w52-735v. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
