Summary
PasswordPusher before 2.8.1 accepts data URI schemes in URL push payloads due to insufficient validation in the valid_url function. Attackers can create malicious pushes containing data:text/html URIs that execute arbitrary JavaScript in victims' browsers when clicked, enabling phishing and credential theft under the trusted PasswordPusher domain.
