Unauthenticated Cross Site Scripting (XSS) in wpDataTables <= 6.5.1.1 versions.
AnalysisAI
Reflected/stored cross-site scripting in the wpDataTables WordPress plugin (versions 6.5.1.1 and earlier) allows unauthenticated remote attackers to inject arbitrary JavaScript that executes in a victim's browser when they view a crafted page or follow a malicious link. The scope-change (S:C) rating in the CVSS vector indicates the injected script can affect resources beyond the vulnerable component - for example the wider WordPress site context - enabling session/cookie theft or admin-panel actions. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV; it was disclosed through Patchstack's vulnerability database.
Technical ContextAI
wpDataTables is a commercial WordPress table/chart-building plugin (vendor CPE: melograno_venture_studio:wpdatatables) used to render sortable, filterable data tables and charts on WordPress sites. The root cause is CWE-79 (Improper Neutralization of Input During Web Page Generation), meaning user-controllable input is reflected or stored into HTML output without adequate output encoding or input sanitization, so browser-interpreted markup and script survive into the rendered page. Because the entry point is reachable without authentication (PR:N), the untrusted data path is exposed to anonymous visitors rather than requiring a logged-in role.
RemediationAI
No exact vendor fix version is stated in the available data, so the specific patched release is not independently confirmed; consult the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/wpdatatables/vulnerability/wordpress-wpdatatables-plugin-6-5-1-1-cross-site-scripting-xss-vulnerability) and the plugin's changelog and upgrade to the first release above 6.5.1.1 as soon as the vendor publishes it. Until a patched version is confirmed and applied, reduce exposure by placing the affected plugin endpoints behind a Web Application Firewall with XSS filtering rules (Patchstack itself offers virtual patching for this CVE), restricting or gating public access to pages that render wpDataTables output, and enabling a strict Content-Security-Policy that disallows inline script to blunt injected payloads - note that a strict CSP can break legitimate inline scripts used by themes/plugins and should be tested in staging. If the plugin is not actively needed, deactivating and removing it eliminates the exposure entirely at the cost of losing table/chart functionality.
