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...

Name of the Vulnerable Software and Affected Versions SurrealDB versions prior to 3.1.0 Description When a JWT access method is configured using the ALGORITHM ES512 parameter within the DEFINE ACCESS statement, the system silently substitutes the ES384 algorithm. This occurs because the underlyin...

SurrealDB: ES512 silently downgraded to ES384 due to jsonwebtoken crate limitation

When a user configures ALGORITHM ES512 for any JWT access method DEFINE ACCESS ... TYPE JWT ALGORITHM ES512, SurrealDB silently substitutes ES384 at all four internal algorithm conversion points. This occurs because the underlying jsonwebtoken crate v10.x does not include an ES512 algorithm...

ALPINE-CVE-2024-31497

In PuTTY 0.68 through 0.80 before 0.81, biased ECDSA nonce generation allows an attacker to recover a user's NIST P-521 secret key via a quick attack in approximately 60 signatures. This is especially important in a scenario where an adversary is able to read messages signed by PuTTY or Pageant...

PuTTY and embedders (f.i., filezilla) -- biased RNG with NIST P521/ecdsa-sha2-nistp521 signatures permits recovering private key

Simon Tatham reports: ECDSA signatures using 521-bit keys the NIST P521 curve, otherwise known as ecdsa-sha2-nistp521 were generated with biased random numbers. This permits an attacker in possession of a few dozen signatures to RECOVER THE PRIVATE KEY. Any 521-bit ECDSA private key that PuTTY or...
