CVE-2024-13657 is a stored cross-site scripting vulnerability in the Store Locator Widget WordPress plugin. It occurs due to improper neutralization of input during web page generation, specifically in the 'storelocatorwidget' shortcode. Authenticated attackers with contributor-level privileges or above can inject malicious scripts via user-supplied shortcode attributes. These scripts execute in the context of any user accessing the injected page, potentially leading to information disclosure or session hijacking. The vulnerability affects all versions up to 2025r1. No patch or vendor advisory indicating a fix is currently available.

Successful exploitation allows authenticated users with contributor or higher privileges to inject persistent malicious scripts into pages using the vulnerable shortcode. These scripts execute in the browsers of users who view the affected pages, potentially leading to limited confidentiality and integrity impacts such as theft of user credentials or manipulation of page content. Availability is not impacted. The vulnerability requires authenticated access but no user interaction to trigger the script execution once the page is viewed.

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 removing the Store Locator Widget plugin if possible. Monitor for updates from the vendor regarding patches or official mitigations.
