{"identifier":"CVE-2026-100158","cve":{"id":"CVE-2026-100158","description":"The SQL Chart Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'X-axis column value ($value->$xarg_s from $wpdb->get_results())' parameter in all versions up to, and including, 3.0.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires an administrator to have published a chart whose SQL query returns a column controllable by a lower-privileged user, such as wp_users.display_name, which a Subscriber can populate with a payload via the standard WordPress profile page at /wp-admin/profile.php.","published":"2026-10-16T06:17:01.323000+00:00","modified":"2026-10-16T15:16:57.950000+00:00","status":"Deferred","score":6.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","cvss_version":"3.1","affected":[],"weaknesses":["CWE-79"],"references":[{"url":"https://plugins.trac.wordpress.org/browser/sql-chart-builder/tags/3.0.6/functions.php#L1019","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/sql-chart-builder/tags/3.0.6/functions.php#L1093","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/sql-chart-builder/tags/3.0.6/functions.php#L1101","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/sql-chart-builder/tags/3.0.6/functions.php#L579","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/sql-chart-builder/tags/3.0.6/functions.php#L820","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3725657%40sql-chart-builder&new=3725657%40sql-chart-builder","source":"security@wordfence.com"},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/16375398-c5c9-465f-9a2f-4c08f76b090b?source=cve","source":"security@wordfence.com"}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"security@wordfence.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","baseScore":6.4,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":3.1,"impactScore":2.7}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-16T14:34:41.886031Z","id":"CVE-2026-100158","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T10:22:56.613989+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00195,"percentile":0.09231,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"plugins.trac.wordpress.org","source_url":"https://plugins.trac.wordpress.org/browser/sql-chart-builder/tags/3.0.6/functions.php#L1019","investigate_url":"https://investigate.aeglixmind.com/#plugins.trac.wordpress.org"},{"domain":"www.wordfence.com","source_url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/16375398-c5c9-465f-9a2f-4c08f76b090b?source=cve","investigate_url":"https://investigate.aeglixmind.com/#www.wordfence.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-100158","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-100158","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-100158","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
