CVE-2026-9243 is a stored cross-site scripting vulnerability in the Plus Addons for Elementor plugin for WordPress, specifically in the Carousel Anything widget. The issue stems from improper neutralization of input during web page generation (CWE-79), where the 'carousel_direction' parameter is inserted into an unquoted HTML attribute (dir=) without sufficient escaping, enabling attribute injection despite the use of esc_attr(). Authenticated attackers with contributor-level privileges or higher can exploit this to inject malicious scripts that execute in the context of users visiting the compromised pages. The CVSS 3.1 base score is 6.4, indicating a medium severity vulnerability with network attack vector, low attack complexity, and no user interaction required.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable 'carousel_direction' parameter. These scripts execute in the browsers of users who view the affected pages, potentially leading to information disclosure or session hijacking. The vulnerability does not impact availability and requires authenticated access, limiting its scope. There are no 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 released, restrict contributor-level access to trusted users only and consider disabling or avoiding use of the Carousel Anything widget. Monitor for updates from the vendor or plugin maintainers regarding patches or official mitigations.
