{"id":"CVE-2026-8689","state":"PUBLISHED","title":"Visualizer: Tables and Charts Manager for WordPress <= 3.11.14 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Chart Creation and Modification via renderChartPages() and uploadData() Functions","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.","publishedAt":"2026-05-28T07:43:43.470Z","updatedAt":"2026-05-28T10:32:10.513Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["themeisle Visualizer: Tables and Charts Manager for WordPress"],"affected":[{"vendor":"themeisle","product":"Visualizer: Tables and Charts Manager for WordPress","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.11.14","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/d18e9696-0f96-4478-9871-a93ac2976c11?source=cve","https://plugins.trac.wordpress.org/browser/visualizer/tags/4.0.1/classes/Visualizer/Module/Chart.php#L531","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#L56","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#L1221","https://plugins.trac.wordpress.org/browser/visualizer/tags/3.11.14/classes/Visualizer/Module/Chart.php#L56","https://plugins.trac.wordpress.org/changeset/3474710"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/8xxx/CVE-2026-8689.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-8689","state":"PUBLISHED","datePublished":"2026-05-28T07:43:43.470Z","dateUpdated":"2026-05-28T10:32:10.513Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-15T14:41:35.110Z"},"containers":{"cna":{"title":"Visualizer: Tables and Charts Manager for WordPress <= 3.11.14 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Chart Creation and Modification via renderChartPages() and uploadData() Functions","descriptions":[{"lang":"en","value":"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.
