python3.9 is vulnerable to Improper Access Control. The vulnerability exists due to a flaw in the way the hmac.compare_digest()
function in the Lib/hmac.py
module compares two message digests. An attacker can exploit this vulnerability to distinguish between different message digests, which could be used to defeat certain cryptographic applications.
