The jonua Table Field Add-on for ACF and SCF plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Authenticated users with Author-level privileges or higher can inject arbitrary JavaScript into table cell content, which is then stored and executed in the context of any user viewing the page containing the injected content. This vulnerability affects all plugin versions up to 1.3.30. The CVSS 3.1 score is 6.4 (medium severity), reflecting network attack vector, low attack complexity, privileges required, no user interaction, and impacts on confidentiality and integrity but not availability. No patch or remediation details are currently provided.

Successful exploitation allows an attacker with Author-level access or higher to execute arbitrary scripts in the browsers of users viewing the compromised pages. This can lead to unauthorized actions performed on behalf of users, data theft, or session hijacking. The impact affects confidentiality and integrity but does not affect availability. There are no known active exploits reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, limit Author-level access to trusted users only and consider removing or disabling the vulnerable plugin if possible. Monitor for plugin updates from the vendor addressing this issue.
