The All-in-One Addons for Elementor – WidgetKit plugin for WordPress contains a stored cross-site scripting vulnerability (CWE-79) in its 'button+modal' widget due to improper neutralization of user-supplied input. Authenticated attackers with contributor or higher privileges can inject arbitrary JavaScript code that executes when other users access the affected pages. This vulnerability affects all versions up to and including 2.5.4. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts on confidentiality and integrity but not availability. There is no indication of an official patch or vendor advisory at this time.

Successful exploitation allows an authenticated contributor or higher to inject persistent malicious scripts into pages, which execute in the context of users viewing those pages. This can lead to unauthorized disclosure of information and modification of content, impacting confidentiality and integrity. Availability is not affected. No known exploits are reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict contributor-level access to trusted users only and consider removing or disabling the vulnerable 'button+modal' widget if possible. Monitor official channels for updates and apply patches promptly once released.
