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...
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...
