The WPZOOM Addons for Elementor – Starter Templates & Widgets plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, the Image Box widget does not adequately sanitize or escape user-supplied attributes, enabling authenticated attackers with contributor-level privileges or above to inject arbitrary web scripts. These scripts execute in the context of any user who accesses the compromised page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all plugin versions up to 1.1.36. The CVSS 3.1 base score is 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, required privileges, no user interaction, scope change, and limited confidentiality and integrity impacts without availability impact.

An authenticated attacker with contributor-level access or higher can inject persistent malicious scripts via the Image Box widget. These scripts execute in the browsers of users visiting the affected pages, potentially leading to theft of user credentials, session tokens, or other sensitive information. The vulnerability impacts confidentiality and integrity but does not affect availability. There is no indication of known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or avoiding use of the vulnerable Image Box widget. Monitor for updates from WPZOOM regarding patches or official mitigations.
