GHSA-g4hp-pfvf-vm5w has a CVSS score of 6.5/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by GHSA-g4hp-pfvf-vm5w?

GHSA-g4hp-pfvf-vm5w affects the following packages: silverstripe/framework (Packagist), silverstripe/framework (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-g4hp-pfvf-vm5w?

Update silverstripe/framework to 3.0.14 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-g4hp-pfvf-vm5w is resolved across your whole dependency graph.

How do I detect GHSA-g4hp-pfvf-vm5w in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for silverstripe/framework. 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.

How do I mitigate GHSA-g4hp-pfvf-vm5w if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-g4hp-pfvf-vm5w?

O3 pinpoints whether GHSA-g4hp-pfvf-vm5w is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-g4hp-pfvf-vm5w actively exploited in the wild?

No public exploit code has been indexed for GHSA-g4hp-pfvf-vm5w yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Real-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

When a secure token parameter is provided to a SilverStripe site (such as isDev or flush) an empty token parameter can be provided in order to bypass normal authentication parameters.

For instance, http://www.mysite.com/?isDev=1&isDevtoken will force a site to dev mode. Alternatively, "flush" could also be used in succession to cause excessive load on a victim site and risk denial of service.

The fix in this case is to ensure that empty tokens fail the validation check.
