The Elementor Site Mailer plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) in all versions up to 1.2.3. The root cause is improper neutralization of input during web page generation, allowing unauthenticated attackers to inject arbitrary scripts. These scripts execute in the context of users who access the injected pages, potentially leading to information disclosure or session hijacking. The CVSS 3.1 base score is 7.2, reflecting network attack vector, low attack complexity, no privileges or user interaction required, and impact on confidentiality and integrity but not availability. No patch or official fix has been documented yet.

Successful exploitation enables an unauthenticated attacker to execute arbitrary scripts in the context of users visiting the affected pages, potentially leading to theft of sensitive information or session tokens. The vulnerability impacts confidentiality and integrity but does not affect availability. There are no known active exploits reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider disabling or removing the vulnerable plugin to prevent exploitation. Monitoring for updates from the vendor is recommended.
