|---|---|---|---|---|---|---|---|
| CVE-2026-39373 | Med | 5.3 | <= 1.5.6 | — | Apr 7, 2026 | JWCrypto implements JWK, JWS, and JWE specifications using python-cryptography. Prior to 1.5.7, an unauthenticated attacker can exhaust server memory by sending crafted JWE tokens with ZIP compression. The existing patch for CVE-2024-28102 limits input token size to 250KB but do | |
| CVE-2024-28102 | — | < 1.5.6 | 1.5.6 | Mar 6, 2024 | JWCrypto implements JWK, JWS, and JWE specifications using python-cryptography. Prior to version 1.5.6, an attacker can cause a denial of service attack by passing in a malicious JWE Token with a high compression ratio. When the server processes this token, it will consume a lot | ||
| CVE-2023-6681 | — | < 1.5.1 | 1.5.1 | Feb 12, 2024 | A vulnerability was found in JWCrypto. This flaw allows an attacker to cause a denial of service (DoS) attack and possible password brute-force and dictionary attacks to be more resource-intensive. This issue can result in a large amount of computational consumption, causing a de | ||
| CVE-2022-3102 | med | — | < 1.4 | 1.4 | Sep 21, 2022 | The JWT code can auto-detect the type of token being provided, and this can lead the application to incorrect conclusions about the trustworthiness of the token. Quoting the private disclosure we received : "Under certain circumstances, it is possible to substitute a [..] signed | |
| CVE-2016-6298 | Med | 5.3 | < 0.3.2 | 0.3.2 | Sep 1, 2016 | The _Rsa15 class in the RSA 1.5 algorithm implementation in jwa.py in jwcrypto before 0.3.2 lacks the Random Filling protection mechanism, which makes it easier for remote attackers to obtain cleartext data via a Million Message Attack (MMA). |
