CVE-2026-44459
3.8 · LOWOverview
CVE-2026-44459 is a low-severity vulnerability affecting hono hono. It was published on May 13, 2026 and has a CVSS 3.1 base score of 3.8 (LOW).
This vulnerability has a CVSS 3.1 base score of 3.8, rated LOW. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.12.18, improper validation of the JWT NumericDate claims exp, nbf, and iat in hono/utils/jwt allows tokens with non-spec-compliant claim values to silently bypass time-based checks. This issue is not exploitable by an anonymous attacker; it only manifests when a malformed claim value reaches verify() — typically when the application itself issues such tokens, or when the signing key is otherwise under attacker control. This vulnerability is fixed in 4.12.18.
Remediation
Check the references section for vendor advisories and patches from hono. Update hono to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
