CVE-2026-81179
HIGHDescription
SysReptor is a fully customizable pentest reporting platform. Prior to 2026.58, installations that enable password reset by email while configuring ALLOWED_HOSTS with a wildcard accept an attacker-controlled Host header when generating a password reset link. An unauthenticated attacker can request a reset email whose link points to an attacker-controlled system, and a victim who follows that link can disclose the reset token, allowing the attacker to reset the victim's password and take over the account. Exploitation also requires a configured email gateway and an email address for the victim, while some reverse proxy configurations may reject the hostile Host header. This issue is fixed in version 2026.58.
