GHSA-3pjv-r7w4-2cf5 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-3pjv-r7w4-2cf5?

GHSA-3pjv-r7w4-2cf5 affects the following packages: org.grails:grails-databinding (Maven), org.grails:grails-databinding (Maven), org.grails:grails-databinding (Maven), org.grails:grails-databinding (Maven). Ecosystems affected: Maven.

How do I fix GHSA-3pjv-r7w4-2cf5?

Update org.grails:grails-databinding to 6.1.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3pjv-r7w4-2cf5 is resolved across your whole dependency graph.

How do I detect GHSA-3pjv-r7w4-2cf5 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.grails:grails-databinding, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-3pjv-r7w4-2cf5 if there is no patch (or I can't update yet)?

Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

Is GHSA-3pjv-r7w4-2cf5 actively exploited in the wild?

No public exploit code has been indexed for GHSA-3pjv-r7w4-2cf5 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-3pjv-r7w4-2cf5?

GHSA-3pjv-r7w4-2cf5 has an EPSS (Exploit Prediction Scoring System) score of 0.7%, placing it in the 54th 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.

What type of vulnerability is GHSA-3pjv-r7w4-2cf5?
