CVE-2026-81888
5.4
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N
Summary
@hono/oauth-providers is Authentication middleware for Hono. Prior to version 0.8.6, the built-in social login providers accept an OAuth callback even when the state value is absent on both sides, so the anti-CSRF check passes for a callback that never came from a genuine login attempt. This defeats the state-based CSRF protection under default usage. Version 0.8.6 has a patch.
