CVE-2026-69247

A flaw was found in cryptography, a Python package for cryptographic primitives. This vulnerability, known as a Bleichenbacher oracle, arises during PKCS7 EnvelopedData decryption. An attacker can exploit distinguishable error messages and timing differences during decryption to gain information...
