Hono · Hono · CVE-2026-56764
**Name of the Vulnerable Software and Affected Versions**
Hono versions prior to 4.11.10
**Description**
The `basicAuth` and `bearerAuth` middlewares are susceptible to a timing attack. This occurs because the `timingSafeEqual()` function performs non-constant-time string comparisons, meaning the process terminates early when a mismatch is found. An attacker can use precise timing measurements of these responses to infer valid credentials.
**Recommendations**
Update to version 4.11.10 or later.
