{"cve":"CVE-2026-8689","nvd":{"published":"2026-05-28T09:16:48.973","modified":"2026-06-17T11:04:17.410","status":"Deferred","description":"The Visualizer: Tables and Charts Manager for WordPress plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.11.14. This is due to a missing capability check on the renderChartPages() and uploadData() functions, where the wp_ajax_visualizer-create-chart and wp_ajax_visualizer-edit-chart AJAX actions invoke renderChartPages() without any current_user_can() check, and wp_ajax_visualizer-upload-data invokes uploadData() which also lacks a capability check and validates its nonce without an action argument, making it trivially bypassable. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create arbitrary chart posts and access or modify chart data belonging to other users, including administrators.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/visualizer/tags/3.11.14/classes/Visualizer/Module/Chart.php#L1221","https://plugins.trac.wordpress.org/browser/visualizer/tags/3.11.14/classes/Visualizer/Module/Chart.php#L531","https://plugins.trac.wordpress.org/browser/visualizer/tags/3.11.14/classes/Visualizer/Module/Chart.php#L56","https://plugins.trac.wordpress.org/browser/visualizer/tags/4.0.1/classes/Visualizer/Module/Chart.php#L1221","https://plugins.trac.wordpress.org/browser/visualizer/tags/4.0.1/classes/Visualizer/Module/Chart.php#L531"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-8689","score":0.00242,"percentile":0.15478,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
