Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @samanhappy/mcphub, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of @samanhappy/mcphub has shipped for GHSA-5q2p-3jg8-2m98 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-5q2p-3jg8-2m98 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-5q2p-3jg8-2m98. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
