CVE-2026-119283

The joserfc Python library, prior to version 1.7.5 , is vulnerable to a CPU exhaustion Denial of Service (DoS) attack. The issue resides in the joserfc.jwe.decrypt_json() function, which processes a JWE General JSON Serialization recipients array without enforcing a count limit. An unauthenticate...

CVE-2026-119283 joserfc: Unbounded JWE General JSON `recipients` Array Leads to CPU Exhaustion (DoS) via Repeated RSA Private-Key Decryption

joserfc is a Python library that provides an implementation of several JSON Object Signing and Encryption JOSE standards. Prior to 1.7.5, joserfc.jwe.decryptjson accepts a JWE General JSON Serialization recipients array without a count limit and calls decryptcek for every entry. An unauthenticate...
