CVE-2026-34073 [LOW] CWE-295 CVE-2026-34073: cryptography is a package designed to expose cryptographic primitives and recipes to Python develope cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to version 46.0.6, DNS name constraints were only validated against SANs within child certificates, and not the "peer name" presented during each validation. Consequently, cryptography would allow a peer named bar.example.com to validate agains

CVE-2026-26007 [HIGH] CWE-345 CVE-2026-26007: cryptography is a package designed to expose cryptographic primitives and recipes to Python develope cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to 46.0.5, the public_key_from_numbers (or EllipticCurvePublicNumbers.public_key()), EllipticCurvePublicNumbers.public_key(), load_der_public_key() and load_pem_public_key() functions do not verify that the point belongs to the expected prime-

CVE-2024-26130 [HIGH] CWE-476 CVE-2024-26130: cryptography is a package designed to expose cryptographic primitives and recipes to Python develope cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Starting in version 38.0.0 and prior to version 42.0.4, if `pkcs12.serialize_key_and_certificates` is called with both a certificate whose public key did not match the provided private key and an `encryption_algorithm` with `hmac_hash` set (via `Pri

CVE-2023-50782 [HIGH] CWE-203 CVE-2023-50782: A flaw was found in the python-cryptography package. This issue may allow a remote attacker to decry A flaw was found in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data.

CVE-2023-49083 [MEDIUM] CWE-476 CVE-2023-49083: cryptography is a package designed to expose cryptographic primitives and recipes to Python develope cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Calling `load_pem_pkcs7_certificates` or `load_der_pkcs7_certificates` could lead to a NULL-pointer dereference and segfault. Exploitation of this vulnerability poses a serious risk of Denial of Service (DoS) for any application attempting to dese

CVE-2023-38325 [HIGH] CWE-295 CVE-2023-38325: The cryptography package before 41.0.2 for Python mishandles SSH certificates that have critical opt The cryptography package before 41.0.2 for Python mishandles SSH certificates that have critical options.

CVE-2023-23931 [MEDIUM] CWE-754 CVE-2023-23931: cryptography is a package designed to expose cryptographic primitives and recipes to Python develope cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In affected versions `Cipher.update_into` would accept Python objects which implement the buffer protocol, but provide only immutable buffers. This would allow immutable objects (such as `bytes`) to be mutated, thus violating fundamental rules of

CVE-2020-36242 [CRITICAL] CWE-190 CVE-2020-36242: In the cryptography package before 3.3.2 for Python, certain sequences of update calls to symmetrica In the cryptography package before 3.3.2 for Python, certain sequences of update calls to symmetrically encrypt multi-GB values could result in an integer overflow and buffer overflow, as demonstrated by the Fernet class.

CVE-2020-25659 [MEDIUM] CWE-385 CVE-2020-25659: python-cryptography 3.2 is vulnerable to Bleichenbacher timing attacks in the RSA decryption API, vi python-cryptography 3.2 is vulnerable to Bleichenbacher timing attacks in the RSA decryption API, via timed processing of valid PKCS#1 v1.5 ciphertext.

CVE-2016-9243 [HIGH] CVE-2016-9243: HKDF in cryptography before 1.5.2 returns an empty byte-string if used with a length less than algor HKDF in cryptography before 1.5.2 returns an empty byte-string if used with a length less than algorithm.digest_size.
