Upgrade org.bitbucket.b_c:jose4j to version 0.9.6 or higher.
Overview
org.bitbucket.b_c:jose4j is a robust and easy to use open source implementation of JSON Web Token (JWT) and the JOSE specification suite (JWS, JWE, and JWK). It is written in Java and relies solely on the JCA APIs for cryptography. Please see https://bitbucket.org/b_c/jose4j/wiki/Home for more info, examples, etc...
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the JSON Web Encryption decompression process. An attacker can exhaust system memory and processing resources by submitting a specially crafted JWE token with a very high compression ratio.
