{"id":"CVE-2026-6972","state":"PUBLISHED","title":"SKT Skill Bar <= 2.6 - Authenticated (Contributor+) Stored Cross-Site Scripting","description":"The SKT Skill Bar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `chart_size` attribute of the `skillwrapper` shortcode in all versions up to, and including, 2.6. This is due to insufficient input sanitization and output escaping on the `chart_size` attribute, which is concatenated directly into an inline `<style>` block. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","publishedAt":"2026-08-05T06:38:01.779Z","updatedAt":"2026-08-05T14:16:31.205Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["sonalsinha21 SKT Skill Bar"],"affected":[{"vendor":"sonalsinha21","product":"SKT Skill Bar","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.6","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/eb689760-837f-45e6-ba51-a834053be6ae?source=cve","https://plugins.trac.wordpress.org/browser/skt-skill-bar/tags/2.6/sktskillbar.php#L240","https://plugins.trac.wordpress.org/browser/skt-skill-bar/trunk/sktskillbar.php#L240","https://plugins.trac.wordpress.org/browser/skt-skill-bar/tags/2.6/sktskillbar.php#L56","https://plugins.trac.wordpress.org/browser/skt-skill-bar/tags/2.6/sktskillbar.php#L541","https://plugins.trac.wordpress.org/changeset?reponame=&new=3565730%40skt-skill-bar%2Ftrunk&old=3565726%40skt-skill-bar%2Ftrunk"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/6xxx/CVE-2026-6972.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-6972","state":"PUBLISHED","datePublished":"2026-08-05T06:38:01.779Z","dateUpdated":"2026-08-05T14:16:31.205Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-24T17:30:26.314Z"},"containers":{"cna":{"title":"SKT Skill Bar <= 2.6 - Authenticated (Contributor+) Stored Cross-Site Scripting","descriptions":[{"lang":"en","value":"The SKT Skill Bar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `chart_size` attribute of the `skillwrapper` shortcode in all versions up to, and including, 2.6.
