joserfc is a Python library that provides an implementation of several JSON Object Signing and Encryption JOSE standards. In 1.6.2 and earlier, a resource exhaustion vulnerability in joserfc allows an unauthenticated attacker to cause a Denial of Service DoS via CPU exhaustion. When the library...
CVE-2026-27932
CVE-2026-27932 affects the Python library joserfc (1.6.2 and earlier). The root cause is an unbounded PBES2 Count (p2c) value read from a JWE protected header, which allows an attacker to trigger CPU exhaustion and Denial of Service by forcing extremely high PBKDF2 iteration counts. Impact is at ...
