CVE-2024-28102Public exploitNetwork attack vector

Service interruption via unbounded JWE decompression

Published Mar 6, 2024 · Updated Sep 9, 2024

Denial of service in Latchset JWCrypto before 1.5.6 allows remote authenticated users to exhaust server CPU and memory via compressed JWE tokens. The JWE decryption path passes DEF-compressed plaintext directly to zlib.decompress without first enforcing a compressed-data size limit. Reachability requires an application to decrypt attacker-controlled compressed JWE data; resource exhaustion interrupts the hosting service.
