The Table Editor plugin for WordPress (wptableeditor) contains a stored cross-site scripting vulnerability identified as CVE-2024-13661. This vulnerability is due to improper neutralization of input during web page generation (CWE-79) specifically in the 'wptableeditor_vtabs' shortcode. Authenticated users with contributor or higher privileges can inject malicious scripts via insufficiently sanitized shortcode attributes. These scripts execute in the context of users visiting the injected pages, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all plugin versions up to 1.5.1. The CVSS 3.1 score is 6.4, reflecting a medium severity with network attack vector, low attack complexity, and requiring privileges but no user interaction.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable shortcode. These scripts execute in the browsers of users who view the compromised pages, potentially allowing theft of session tokens, defacement, or other client-side attacks. The impact is limited by the requirement for authenticated access with contributor privileges or above. There is no indication of impact on availability or server integrity.

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 removing the Table Editor plugin if not essential. Monitor for plugin updates that address this vulnerability and apply them promptly once available.
