JWX is vulnerable to Denial of Service (DoS). The vulnerability is caused due improper checking of the decompressed data size, allowing an attacker to craft a malicious input with an exceptionally high compression ratio, leading to a Denial of Service (DoS) condition by consuming excessive memory during decompression.
