Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Nimbus JOSE+JWT (com.nimbusds:nimbus-jose-jwt) versions before 9.37.2 are vulnerable to denial of service. An attacker who can submit a JWE token to an application that uses PasswordBasedDecrypter can supply a very large p2c (PBKDF2 iteration count) header value, consuming excessive resources during decryption. Upgrade to version 9.37.2 or later.
