The SnapWidget Social Photo Feed Widget versions up to 1.1.0 suffer from a DOM-based Cross-site Scripting vulnerability due to improper input neutralization during web page generation. This vulnerability allows attackers with low privileges to execute arbitrary scripts by tricking users into interacting with crafted content. The CVSS 3.1 score is 6.5 (medium severity), reflecting network attack vector, low attack complexity, required privileges, user interaction, and partial impacts on confidentiality, integrity, and availability. No patch or vendor advisory is currently available, and the product is not a cloud service, so remediation depends on vendor updates.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to partial disclosure of information, modification of data, or disruption of service. The attack requires user interaction and low privileges but can affect the confidentiality, integrity, and availability of the application environment. 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 released, users should consider limiting exposure by restricting access to the widget or disabling it if feasible. Monitor for updates from SnapWidget and apply patches promptly once available.
