CVE-2026-26273: Known affected by Account Takeover via Password Reset Token Leakage

February 13, 2026

A Critical Broken Authentication vulnerability exists in Known 1.6.2. The application leaks the password reset token within a hidden HTML input field on the password reset page. This allows any unauthenticated attacker to retrieve the reset token for any user by simply querying the user’s email, leading to full Account Takeover (ATO) without requiring access to the victim’s email inbox.
