CVE-2024-29370 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. In python-jose 3.3.0 (specifically jwe.decrypt), a vulnerability allows an attacker to cause a Denial-of-Service (DoS) condition by crafting a malicious JSON Web Encryption (JWE) token with an exceptionally high compression ratio. When this token is processed by the server, it results in significant memory allocation and processing time during decompression.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
