CVE-2024-1398 is a stored cross-site scripting vulnerability in the Ultimate Bootstrap Elements for Elementor WordPress plugin. It affects all versions up to 1.3.6 due to improper neutralization of input in the 'heading_title_tag' and 'heading_sub_title_tag' parameters. Authenticated attackers with contributor or higher privileges can inject arbitrary JavaScript that executes in the context of users viewing the compromised pages. This vulnerability is classified under CWE-79 and has a CVSS 3.1 base score of 6.4, reflecting a medium severity level with network attack vector, low attack complexity, and no user interaction required.

Successful exploitation allows an authenticated contributor or higher user to inject persistent malicious scripts into pages, which execute when other users access those pages. This can lead to limited confidentiality and integrity impacts, such as session hijacking or content manipulation. There is no direct impact on availability. No known exploits are reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level permissions to trusted users only and consider disabling or limiting use of the affected plugin. Monitor for updates from the vendor or plugin repository to apply any forthcoming patches promptly.
