MEDIUM 6.3EPSS 0.33%

Does this matter?

Lower severity and a low EPSS score (0.33%). Track it; it rarely justifies an emergency change on its own.

Description

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.
