This vulnerability in WeShare Buttons e-mailit plugin allows stored XSS due to improper input neutralization during web page generation. Attackers could inject malicious scripts that persist and execute when other users access affected pages. The flaw affects all versions up to 13.0.0. The CVSS vector indicates network attack vector, low attack complexity, high privileges required, user interaction required, scope changed, and low impact on confidentiality, integrity, and availability.

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 limited confidentiality, integrity, and availability impacts. No known exploits in the wild have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to high-privilege users and limit user interaction with untrusted content in the affected plugin. Monitor vendor channels for updates.
