This vulnerability in Vertex Addons for Elementor involves improper input sanitization leading to stored XSS. Attackers can inject malicious scripts that persist in the application and execute when viewed by other users. The affected versions include all releases up to 1.2.0. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with impacts on confidentiality, integrity, and availability rated as low to low to low respectively.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to information disclosure, session hijacking, or other impacts on confidentiality, integrity, and availability. However, the medium severity and CVSS score reflect that exploitation requires some privileges and user interaction, limiting the ease and scope of impact.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider restricting privileges and limiting user interactions that could trigger the vulnerability. Monitor vendor channels for updates regarding patches or official mitigations.
