The Visualizer: Tables and Charts Manager for WordPress plugin is vulnerable to Stored Cross-Site Scripting (XSS) due to insufficient input sanitization and output escaping on user-supplied attributes. This vulnerability allows authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages. These scripts execute whenever a user accesses an injected page, creating significant risk for affected WordPress sites.
The CVSS score for this vulnerability is 6.4, categorizing it as medium severity. The characteristics include a network attack vector, low attack complexity, and low privileges required. Organizations should understand that the risk to organizations includes potential unauthorized access and manipulation of user data.
As of now, there is no public exploit confirmed, but the vulnerability exists in all versions of the plugin up to and including version 3.11.8. Organizations utilizing this plugin are urged to assess their exposure and implement mitigation strategies.
Organizations should prioritize patching immediately. The plugin developers have been notified, and a fix is expected soon.
