CVE-2024-29371Public exploitNetwork attack vector

Service interruption via unbounded JWE decompression

Published Dec 17, 2025 · Updated Dec 17, 2025

Denial of service in jose4j before 0.9.6 allows remote attackers to interrupt applications by submitting a highly compressed JWE. The DeflateRFC1951CompressionAlgorithm.decompress method expands attacker-controlled JWE content without a decompressed-size limit, consuming memory and CPU. Exposure requires an application to accept and decrypt compressed JWEs; the documented consequence is resource exhaustion and service interruption.
