A security update for python-jwcrypto addresses a vulnerability (CVE-2026-39373) involving weak mitigation against a JWT bomb attack in the deserialize function. This flaw can lead to memory exhaustion when processing crafted compressed JWE tokens. The issue affects certain versions of python-jwcrypto distributed with Red Hat Enterprise Linux 10 and related SUSE products. Red Hat has released patches to fix this vulnerability and rated the security impact as low. No known exploits are reported in the wild.

JWCrypto implements JWK, JWS, and JWE specifications using python-cryptography. Prior to 1.5.7, an unauthenticated attacker can exhaust server memory by sending crafted JWE tokens with ZIP compression. The existing patch for CVE-2024-28102 limits input token size to 250KB but does not validate the decompressed output size. An unauthenticated attacker can cause memory exhaustion on memory-constrained systems. A token under the 250KB input limit can decompress to approximately 100MB. This vulnerability is fixed in 1.5.7.
