Which packages are affected by GHSA-9vrw-m88g-w75q?

GHSA-9vrw-m88g-w75q affects the following packages: @hapi/accept (npm), @hapi/accept (npm). Ecosystems affected: npm.

How do I fix GHSA-9vrw-m88g-w75q?

Update @hapi/accept to 3.2.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9vrw-m88g-w75q is resolved across your whole dependency graph.

How do I detect GHSA-9vrw-m88g-w75q in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @hapi/accept. 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.

How do I mitigate GHSA-9vrw-m88g-w75q if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-9vrw-m88g-w75q?

O3 pinpoints whether GHSA-9vrw-m88g-w75q is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-9vrw-m88g-w75q actively exploited in the wild?

No public exploit code has been indexed for GHSA-9vrw-m88g-w75q 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.

📦@hapi/accept📦@hapi/accept

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects npm packages — download data is not available via public APIs for these ecosystems.

Description

Versions of @hapi/accept prior to 3.2.4 or 5.0.1 are vulnerable to Denial of Service. The Accept-Encoding HTTP header parser has a vulnerability which will cause the function to throw a system error if the header contains some invalid values. Because hapi rethrows system errors (as opposed to catching expected application errors), the error is thrown all the way up the stack. If no unhandled exception handler is available, the application will exist, allowing an attacker to shut down services.

Recommendation

Upgrade to version 3.2.4 or 5.0.1.
