CVE-2026-67336

better-auth versions before 1.6.11 contain insecure cryptographic defaults in the oidcProvider and mcp plugins that advertise the none algorithm and accept plain PKCE by default. Attackers can exploit algorithm negotiation to accept unsigned tokens or intercept authorization codes when PKCE plain...

CVE-2026-67336

CVE-2026-67336 affects better-auth versions before 1.6.11, specifically the oidcProvider and mcp plugins. The root cause is insecure cryptographic defaults that advertise the none algorithm and allow plain PKCE by default. This can enable an attacker to exploit algorithm negotiation to accept uns...

CVE-2026-67336 better-auth before 1.6.11 Insecure Cryptographic Defaults via oidcProvider

better-auth versions before 1.6.11 contain insecure cryptographic defaults in the oidcProvider and mcp plugins that advertise the none algorithm and accept plain PKCE by default. Attackers can exploit algorithm negotiation to accept unsigned tokens or intercept authorization codes when PKCE plain...

CVE-2026-27804

Parse Server versions prior to 8.6.3 and 9.1.1-alpha.4 are vulnerable to unauthenticated login via forged Google tokens (alg: none). The root cause is trusting the JWT header for algorithm selection; the fix hardcodes RS256 and shifts key validation to jwks-rsa, rejecting unknown key IDs. Affecte...

Astra Linux – Vulnerability in Ceph

Ceph is a distributed object, block, and file storage platform. In versions 19.2.3 and earlier, it is possible to send a JWT with “none” as its JWT algorithm. By doing this, the JWT signature is not checked. The vulnerability lies most likely in the RadosGW OIDC provider. As of the time of...
