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...
GHSA-9H47-PQCX-HJR4 Better Auth has insecure cryptographic defaults in oidcProvider: alg=none advertised and plain PKCE accepted by default
Am I affected? Users are affected if all of the following are true: - Their application uses better-auth at a version below the patched release. - Their application enables oidcProvider from better-auth/plugins/oidc-provider or mcp from better-auth/plugins/mcp the mcp plugin delegates to...
CVE-2026-39413
LightRAG provides simple and fast retrieval-augmented generation. Prior to 1.4.14, the LightRAG API is vulnerable to a JWT algorithm confusion attack where an attacker can forge tokens by specifying 'alg': 'none' in the JWT header. Since the jwt.decode call does not explicitly deny the 'none'...
CVE-2026-39413 LightRAG has a JWT Algorithm Confusion Vulnerability in LightRAG API

lightrag-hku: JWT Algorithm Confusion Vulnerability
Summary The LightRAG API is vulnerable to a JWT algorithm confusion attack where an attacker can forge tokens by specifying 'alg': 'none' in the JWT header. Since the jwt.decode call does not explicitly deny the 'none' algorithm, a crafted token without a signature will be accepted as valid,...

Name of the Vulnerable Software and Affected Versions Authlib versions 1.6.5 through 1.6.7 Description Authlib, a Python library for building OAuth and OpenID Connect servers, had a flaw in signature verification. Specifically, tests involving a malicious JWT with 'alg: none' and an empty signatu...
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...
jose-swift has JWT Signature Verification Bypass via None Algorithm
Summary An authentication bypass vulnerability allows any unauthenticated attacker to forge arbitrary JWT tokens by setting "alg": "none" in the token header. The library's verification functions immediately return true for such tokens without performing any cryptographic verification, enabling...
