First version without a known vulnerability: 3.4.0
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.
python-jose algorithm confusion with OpenSSH ECDSA keys
Fixed in: 3.4.0
python-jose denial of service via compressed JWE content
Fixed in: 3.4.0
