6 high-severity fixes in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Cryptography Issue: The secp256k1 public key expansion used incorrect coordinate getters (accessing undefined px and py properties), potentially rendering key expansion and downstream signature verification processes incorrect or insecure.
Denial of Service: Untrusted, serialized keys containing arbitrary Scrypt key derivation parameters could force extreme CPU and memory consumption, leading to resource exhaustion attacks unless restricted to an explicit allowlist.
Auth Bypass: Improper routing and validation of signature types within multi-signature and generic signature verification routines could lead to authentication bypass if ECDSA or other signature algorithms are misclassified.
