CRITICALSupply chain compromise via malicious @cap-js/openapi
Blast Radius
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
@cap-js/openapinpmDescription
Impact
On May 19, 2026, a compromised version of @cap-js/[email protected] was published. The malicious packages harvested credentials and attempted self-propagation. If a compromised version was installed, all credentials accessible on that machine (npm tokens, cloud provider credentials, SSH keys, GitHub PATs) should be considered compromised.
Patches
Upgrade to @cap-js/openapi >= 1.4.2 If the compromised version was ever installed, rotate all affected credentials.
Workarounds
No workarounds.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @cap-js/openapi. 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.
Fix
Update @cap-js/openapi to 1.4.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jpvj-wpmj-h7rv 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 pinpoints whether GHSA-jpvj-wpmj-h7rv is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-jpvj-wpmj-h7rv. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-jpvj-wpmj-h7rv in your dependencies?
O3 detects GHSA-jpvj-wpmj-h7rv across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
