Security readout for executives and security teams
Plain-English summary
CVE-2026-24473 affects Hono applications using the Cloudflare Workers serve static middleware before version 4.11.7. A path validation flaw may let an unauthenticated attacker read unintended internal asset keys from the Workers environment. The issue is patched in Hono 4.11.7.
Executive priority
Treat as a targeted medium-priority update for teams running Hono on Cloudflare Workers. The business risk is unintended disclosure of internal asset keys, not full system compromise based on available evidence. Upgrade during the next expedited dependency maintenance window.
Technical view
Improper validation of user-controlled paths in Hono’s serve static middleware for the Cloudflare Workers adapter can cause information disclosure. The CVE lists CWE-200, CWE-284, and CWE-668. CVSS v4.0 is 6.3, with network attack vector, no privileges or user interaction, high attack complexity, and low confidentiality impact.
Likely exposure
Exposure is likely limited to Hono versions before 4.11.7 where the Cloudflare Workers adapter’s serve static middleware is used. Other Hono deployments are not identified as affected in the provided sources.
Exploitation context
The source bundle does not report active exploitation, and this CVE is not listed as KEV. Exploitation is network-reachable and unauthenticated, but the CVSS vector marks attack complexity as high and impact as limited to confidentiality.
Researcher notes
The public record identifies the vulnerable component and patched version, but does not include broader affected-runtime claims. Avoid assuming impact outside Cloudflare Workers serve static middleware. The referenced commit and advisory are the primary materials for root-cause and patch review.
Mitigation direction
- Upgrade Hono to version 4.11.7 or later.
- Prioritize Cloudflare Workers applications using Hono serve static middleware.
- Review the GitHub advisory and release notes for vendor-specific guidance.
- If immediate upgrade is blocked, reduce exposure of affected static-serving routes where feasible.
Validation and detection
- Inventory applications using the hono package.
- Confirm deployed Hono versions are 4.11.7 or later.
- Identify Cloudflare Workers deployments using Hono serve static middleware.
- Review dependency lockfiles and build artifacts for older Hono versions.
- Check application logs for unusual requests to static asset routes.
