cryptography: cryptography Subgroup Attack Due to Missing Subgroup Validation for SECT Curves

A validation flaw has been discovered in the python cryptography package. This missing validation allows an attacker to provide a public key point P from a small-order subgroup. This can lead to security issues in various situations, such as the most commonly used signature verification ECDSA and...

Amazon tough 数据伪造问题漏洞

Amazon Tough is a Rust client library for The Update Framework TUF by Amazon Inc. Versions of Amazon Tough prior to v0.22.0 contained a data manipulation vulnerability. This vulnerability stemmed from improper validation of the encryption signature uniqueness during delegated role verification. A...

CVE-2026-33471

nimiq-block contains block primitives to be used in Nimiq's Rust implementation. SkipBlockProof::verify computes its quorum check using BitSet.len, then iterates BitSet indices and casts each usize index to u16 slot as u16 for slot lookup. Prior to version 1.3.0, if an attacker can get a...

CVE-2026-5466

wolfSSL's ECCSI signature verifier wcVerifyEccsiHash decodes the r and s scalars from the signature blob via mpreadunsignedbin with no check that they lie in 1, q-1. A crafted forged signature could verify against any message for any identity, using only publicly-known constants...

Improper Verification Of Cryptographic Signature

node-forge is vulnerable to Improper Verification of Cryptographic Signature. The vulnerability is due to insufficient validation of RSASSA PKCS1 v1.5 signatures allowing malformed ASN structures and inadequate padding checks, which allows an attacker to forge valid signatures and bypass signatur...
