python-cryptography: python-cryptography: PKCS#7 EnvelopedData decryption exposes a Bleichenbacher oracle through distinguishable errors and timing

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...

CVE-2026-6291: Observable Timing Discrepancy

Bleichenbacher padding oracle in PKCS7 KTRI decryption. When decrypting PKCS7 EnvelopedData using RSA PKCS1 v1.5 key transport, wolfSSL returned distinguishable error codes depending on whether RSA padding validation failed versus whether the decrypted content was malformed. An attacker able to...
