n8n: Google Service Account Private Key Exposed in JWT Header

Impact When n8n was configured with a Google Service Account key, the full PEM private key was mistakenly placed in the JWT header's kid field which should only have held a key identifier. Since JWT headers were Base64-encoded rather than encrypted, the key could be recovered by anything that...

CVE-2026-65595 n8n before 2.29.8 and 2.30.1 Privilege Escalation via Token Exchange

n8n before 2.30.1 and 2.29.8 assigns all Public API key scopes to JWTs issued through the Token Exchange module regardless of the acting user's role. On instances where the Token Exchange feature and Public API are enabled, a low-privileged user who can obtain a valid external JWT trusted by a...

CVE-2026-47410

Summary of findings: CVE-2026-47410 affects PraisonAI Platform. When PLATFORM_JWT_SECRET is unset and PLATFORM_ENV remains default, the code uses a hardcoded secret dev-secret-change-me to sign and verify JWTs. This enables an attacker to forge tokens for arbitrary users and impersonate workspace...

joserfc: joserfc: Integrity bypass via forged HMAC-signed tokens

A flaw was found in the joserfc Python library. A remote attacker can exploit a vulnerability in the joserfc.jwt.decode function to forge HMAC-signed tokens. This occurs because the library accepts tokens signed with an empty or null verification key, allowing an attacker to bypass integrity...

CVE-2026-63761 SurrealDB before 3.1.0 Algorithm Downgrade via ES512

SurrealDB before 3.1.0 silently substitutes the ES384 algorithm when a JWT access method is configured with ALGORITHM ES512 DEFINE ACCESS ... TYPE JWT ALGORITHM ES512, because the underlying jsonwebtoken crate v10.x has no ES512 variant and the mapping defaults to ES384 without any error, warning...
