Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/fkie-cad/yapscan, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/fkie-cad/yapscan to 0.19.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wxwq-525w-hcqx 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-wxwq-525w-hcqx can be triaged on real exposure rather than presence alone.
Tailored to GHSA-wxwq-525w-hcqx. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
