How severe is GHSA-23vw-mhv5-grv5?

No CVSS score has been assigned to GHSA-23vw-mhv5-grv5 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-23vw-mhv5-grv5?

GHSA-23vw-mhv5-grv5 affects the following packages: @hapi/hapi (npm), @hapi/hapi (npm). Ecosystems affected: npm.

How do I fix GHSA-23vw-mhv5-grv5?

Update @hapi/hapi to 18.4.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-23vw-mhv5-grv5 is resolved across your whole dependency graph.

How do I detect GHSA-23vw-mhv5-grv5 in my npm dependencies?

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

How do I mitigate GHSA-23vw-mhv5-grv5 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-23vw-mhv5-grv5 actively exploited in the wild?

No public exploit code has been indexed for GHSA-23vw-mhv5-grv5 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.

Description

Versions of @hapi/hapi prior to 18.4.1 or 19.1.1 are vulnerable to Denial of Service. The CORS request handler has a vulnerability which will cause the function to throw a system error if the header contains some invalid values. If no unhandled exception handler is available, the application will exist, allowing an attacker to shut down services.

Recommendation

Upgrade to versions 18.4.1, 19.1.1 or later.
