This vulnerability in Cresta Addons for Elementor (<= 1.0.9) is a stored cross-site scripting (XSS) flaw caused by improper input neutralization during web page generation. An attacker with low privileges and requiring user interaction can inject malicious scripts that execute in the context of other users, potentially leading to partial compromise of confidentiality, integrity, and availability. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) reflects network attack vector, low attack complexity, low privileges required, user interaction needed, scope change, and low impact on confidentiality, integrity, and availability.

Successful exploitation allows an attacker to execute arbitrary scripts in the context of affected users, potentially leading to partial disclosure of sensitive information, modification of data, or disruption of service. The vulnerability requires low privileges and user interaction but can affect the security context of other users due to scope change. 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 plugin usage or applying manual input sanitization if feasible. Monitor vendor channels for updates and apply patches promptly once available.
