CVE-2024-28102 is an uncontrolled resource-consumption vulnerability in JWCrypto versions earlier than 1.5.6. Processing a malicious JSON Web Encryption (JWE) token with a high compression ratio can cause excessive memory allocation and CPU consumption during decompression. JWCrypto 1.5.6 introduced a maximum token-length limit to address the issue.

A memory exhaustion vulnerability in JWCrypto's handling of crafted JWE tokens with ZIP compression, where the prior fix for CVE-2024-28102 limited compressed input size but failed to validate decompressed output size, allowing unauthenticated denial of service on memory-constrained systems.
An uncontrolled resource consumption denial-of-service vulnerability in python-jwcrypto/JWCrypto where a malicious highly compressed JWE token can exhaust memory and CPU resources.
A resource-exhaustion denial-of-service vulnerability in the JavaScript jose library's JWE decryption/decompression handling. Crafted JWE content can cause excessive CPU or memory consumption after decryption.
A denial-of-service vulnerability in jwcrypto whereby a malicious JWE token can cause denial of service, fixed through the Red Hat Ansible Automation Platform automation-controller update.
