RoutineCVE-2026-39373latchset · jwcrypto +23 moreJWCrypto: JWE ZIP decompression bombJWCrypto 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 does not validate the decompressed output size. An unauthenticated attacker can cause memory exhaustion on memory-constrained systems. A token under the 250KB input limit can decompress to approximately 100MB. This vulnerability is fixed in 1.5.7.CVSS5.3MediumEPSS0.29%RoutineCVE-2024-28102debian · debian_linux +8 moreJWCrypto vulnerable to JWT bomb Attack in `deserialize` functionJWCrypto 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 of memory and processing time. Version 1.5.6 fixes this vulnerability by limiting the maximum token length.CVSS6.8MediumEPSS0.98%RoutineCVE-2023-6681fedoraproject · fedora +11 moreJwcrypto: denail of service via specifically crafted jweA 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 denial of service attack.CVSS5.3MediumEPSS0.88%RoutineCVE-2016-6298latchset · jwcrypto +3 morelatchset jwcryptoThe _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).CVSS5.3MediumEPSS2.25%
