CVE-2026-63761

SurrealDB before 3.1.0 uses JWT ES512 but internally maps to ES384 because jsonwebtoken v10.x has no ES512. This causes authentication handshake failures when a P-521 key for ES512 is used and can lead to tokens being rejected by systems expecting genuine ES512 signatures. The vulnerability descr...
