CVE-2026-22817

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.11.4, there is a flaw in Hono’s JWK/JWKS JWT verification middleware allowed the JWT header’s alg value to influence signature verification when the selected JWK did not explicitly specify an algorith...

CVE-2026-22818

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.11.4, there is a flaw in Hono’s JWK/JWKS JWT verification middleware allowed the algorithm specified in the JWT header to influence signature verification when the selected JWK did not explicitly defi...

Hono JWK Auth Middleware has JWT algorithm confusion when JWK lacks "alg" (untrusted header.alg fallback)

Summary A flaw in Hono’s JWK/JWKS JWT verification middleware allowed the algorithm specified in the JWT header to influence signature verification when the selected JWK did not explicitly define an algorithm. This could enable JWT algorithm confusion and, in certain configurations, allow forged...

Improper Verification of Cryptographic Signature

Overview hono is an Ultrafast web framework for the Edges Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to the JWT verification middleware fallback on unverified JWT header when alg field is not present. An attacker can gain unauthorized...

Hono JWT Middleware's JWT Algorithm Confusion via Unsafe Default (HS256) Allows Token Forgery and Auth Bypass

Summary A flaw in Hono’s JWK/JWKS JWT verification middleware allowed the JWT header’s alg value to influence signature verification when the selected JWK did not explicitly specify an algorithm. This could enable JWT algorithm confusion and, in certain configurations, allow forged tokens to be...

Use of a Broken or Risky Cryptographic Algorithm

Overview hono is an Ultrafast web framework for the Edges Affected versions of this package are vulnerable to Use of a Broken or Risky Cryptographic Algorithm due to the JWT verification middleware using unsafe default fallback algorithm. An attacker can gain unauthorized access or escalate...

CVE-2026-23478

Cal.com CVE-2026-23478 affects versions 3.1.6–6.0.6. Root cause: improper server-side validation in a custom NextAuth JWT callback that trusts client-supplied data during session.update(), enabling an unauthenticated attacker to fully impersonate any user. Impact: total account takeover with acce...

CVE-2026-23478 Cal.com has an Authentication Bypass via Unvalidated Email in Custom JWT Callback

Cal.com is open-source scheduling software. From 3.1.6 to before 6.0.7, there is a vulnerability in a custom NextAuth JWT callback that allows attackers to gain full authenticated access to any user's account by supplying a target email address via session.update. This vulnerability is fixed in...
