| CVE-2026-39892 | NGHIÊM TRỌNG9.8 | cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. From 45.0.0 to before 46.0.7, if a non-contiguous buffer was passed to APIs which accepted Python buffers (e.g. Hash.update()), this could lead to buffer overflows. This vulnerability is fixed in 46.0.7. | 08/04/2026 |
| CVE-2026-34073 | TRUNG BÌNH5.3 | 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 | 31/03/2026 |
| CVE-2026-26007 | TRUNG BÌNH6.5 | 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 poi | 10/02/2026 |
| CVE-2024-26130 | CAO7.5 | 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_algorith | 21/02/2024 |
| CVE-2023-50782 | CAO7.5 | 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. | 05/02/2024 |
| CVE-2023-49083 | CAO7.5 | 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 | 29/11/2023 |
| CVE-2023-38325 | CAO7.5 | The cryptography package before 41.0.2 for Python mishandles SSH certificates that have critical options. | 14/07/2023 |
| CVE-2023-23931 | TRUNG BÌNH6.5 | 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 | 07/02/2023 |
| CVE-2020-36242 | NGHIÊM TRỌNG9.1 | 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. | 07/02/2021 |
| CVE-2020-25659 | TRUNG BÌNH5.9 | 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. | 11/01/2021 |
| CVE-2016-9243 | CAO7.5 | HKDF in cryptography before 1.5.2 returns an empty byte-string if used with a length less than algorithm.digest_size. | 27/03/2017 |
