This vulnerability in FormLift for Infusionsoft Web Forms allows an attacker with at least low privileges and user interaction to inject and store malicious scripts due to improper input sanitization during web page generation. When other users access the affected web pages, the stored malicious scripts can execute, potentially leading to partial confidentiality, integrity, and availability impacts. The CVSS vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with scope changed and low impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to theft of user data, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability to a limited extent. The medium severity reflects these moderate risks. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider restricting privileges and carefully validating and sanitizing inputs where possible. Monitor vendor channels for updates regarding patches or official mitigations.
