How do I fix GHSA-qw4w-vq8v-2wcv?

Update silverstripe/framework to 4.11.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qw4w-vq8v-2wcv is resolved across your whole dependency graph.

How do I detect GHSA-qw4w-vq8v-2wcv 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-qw4w-vq8v-2wcv 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-qw4w-vq8v-2wcv?

O3 pinpoints whether GHSA-qw4w-vq8v-2wcv 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-qw4w-vq8v-2wcv actively exploited in the wild?

No public exploit code has been indexed for GHSA-qw4w-vq8v-2wcv 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.

What is the EPSS score for GHSA-qw4w-vq8v-2wcv?

GHSA-qw4w-vq8v-2wcv has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 40th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was GHSA-qw4w-vq8v-2wcv published, and has it been updated?

GHSA-qw4w-vq8v-2wcv was published on November 21, 2022 and was last updated on February 20, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
