Red Hat Ansible Automation Platform 2: resource exhaustion
Medium5.9CVE-2026-80179 · Published Aug 28, 2026 · updated Aug 31, 2026
A flaw was found in jwcrypto. A remote attacker can send a specially crafted JSON Web Encryption (JWE) token containing numerous period delimiters. This malformed token can force the JWE.deserialize() function to allocate excessive memory, leading to a MemoryError. This issue results in a denial of service (DoS) for services that process untrusted JWE values.
