This vulnerability involves improper input sanitization in the Proof Factor – Social Proof Notifications plugin by Proof Factor LLC, leading to stored cross-site scripting (XSS). An attacker could inject malicious scripts that persist within the application and execute when other users view the affected content. The vulnerability affects all versions up to 1.0.5. The CVSS 3.1 vector indicates network attack vector, low attack complexity, high privileges required, user interaction required, scope changed, and impacts confidentiality, integrity, and availability at a low level.

Successful exploitation could allow an attacker with high privileges and requiring user interaction to execute arbitrary scripts in the context of the affected application, potentially leading to partial compromise of confidentiality, integrity, and availability of the application data. However, the impact is rated medium due to the required privileges and user interaction.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided. Until a patch is available, users should exercise caution with input handling and consider limiting privileges of users who can submit content. Monitor vendor communications for updates.
