How do I fix GHSA-w332-q679-j88p?

Update hono to 4.11.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-w332-q679-j88p is resolved across your whole dependency graph.

How do I detect GHSA-w332-q679-j88p in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for hono. 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-w332-q679-j88p 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-w332-q679-j88p?

O3 pinpoints whether GHSA-w332-q679-j88p 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-w332-q679-j88p actively exploited in the wild?

No public exploit code has been indexed for GHSA-w332-q679-j88p 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.

What is the EPSS score for GHSA-w332-q679-j88p?

GHSA-w332-q679-j88p has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 33th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-w332-q679-j88p?

GHSA-w332-q679-j88p is classified as Information Exposure (CWE-200), CWE-284 (CWE-284), CWE-668 (CWE-668). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-w332-q679-j88p published, and has it been updated?

GHSA-w332-q679-j88p was published on January 27, 2026 and was last updated on February 12, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Summary

Serve static Middleware for the Cloudflare Workers adapter contains an information disclosure vulnerability that may allow attackers to read arbitrary keys from the Workers environment. Improper validation of user-controlled paths can result in unintended access to internal asset keys.

Details

The vulnerability exists in the serve-static middleware used with the Cloudflare Workers adapter. When serving static assets, the middleware does not sufficiently validate or restrict user-supplied paths before resolving them against the Workers asset storage.

As a result, an attacker may craft requests that access arbitrary keys beyond the intended static asset scope. This issue only affects applications running on Cloudflare Workers that use Serve static Middleware with user-controllable request paths.

Impact

This vulnerability may lead to information disclosure by allowing unauthorized access to internal assets or data stored in the Workers environment. The exposed data is limited to readable asset keys and does not allow modification of stored data or execution of arbitrary code.

The impact is limited to applications that use Serve static Middleware in the Cloudflare Workers adapter and rely on it to safely handle untrusted request paths.
