Description
A Host Header Injection vulnerability in the password reset component in axewater sharewarez v2.4.3 allows remote attackers to conduct password reset poisoning and account takeover via manipulation of the Host header when Flask's url_for(_external=True) generates reset links without a fixed SERVER_NAME.
