CVE-2025-66017: Use of a Broken or Risky Cryptographic Algorithm

CGGMP24 is a state-of-art ECDSA TSS protocol that supports 1-round signing requires 3 preprocessing rounds, identifiable abort, and a key refresh protocol. In versions 0.6.3 and prior of cggmp21 and version 0.7.0-alpha.1 of cggmp24, presignatures can be used in the way that significantly reduces...

A Single-Root, Multi-Curve, Context-Isolated, PQC-Pluggable Cryptographic Identity Primitive with Stateless Secret Rotation

Cryptographic identity anchors modern decentralized systems, yet current standards like BIP-39 and BIP-32 are structurally insufficient for the demands of multi-curve, multi-domain, and post-quantum PQC environments. These legacy schemes rely on a monolithic identity root with no inherent context...

CVE-2025-11934

Improper input validation in the TLS 1.3 CertificateVerify signature algorithm negotiation in wolfSSL 5.8.2 and earlier on multiple platforms allows for downgrading the signature algorithm used. For example when a client sends ECDSA P521 as the supported signature algorithm the server previously...

CVE-2025-11934

CVE-2025-11934 concerns wolfSSL’s TLS 1.3 CertificateVerify signature algorithm negotiation. The vulnerability stems from improper input validation that can downgrade the negotiated signature algorithm (e.g., client supports ECDSA P521 but server accepts and uses ECDSA P256), potentially weakenin...

An issue was discovered in Mbed TLS before 2.25.0 and before 2.16.9 LTS and before 2.7.18 LTS. A NULL algorithm parameters entry looks identical to an array of REAL size zero and thus the certificate is considered valid. However, if the parameters do not match in any way, then the certificate...
