The bs_tcontent() shortcode handler in inc/bs_tabs.php emits the id attribute value into an unquoted HTML attribute. esc_attr() is applied, but it does not encode space characters, so a space in the supplied value terminates the attribute and any following text is parsed as additional HTML attributes, including JavaScript event handlers. This allows authenticated attackers with Contributor-level access and above to inject arbitrary web script that executes in the browser of any user who views the page and interacts with the injected element.","publishedAt":"2026-10-18T22:39:46.933Z","updatedAt":"2026-10-19T16:20:39.966Z","severity":{"score":5.1,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:L/VA:N/SC:L/SI:L/SA:N","source":"mitre"},"assigner":"mitre","products":["Bootstrap Shortcodes project Bootstrap Shortcodes"],"affected":[{"vendor":"Bootstrap Shortcodes project","product":"Bootstrap Shortcodes","packageName":"bootstrap-shortcodes","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"3.4.6","versionType":"semver"}],"collectionURL":"https://wordpress.org/plugins","modules":["bs_tcontent shortcode"],"programFiles":["inc/bs_tabs.php"],"programRoutines":[{"name":"bs_tcontent shortcode"}],"repo":"https://github.com/TheWebShop/bootstrap-shortcodes"}],"references":["https://github.com/TheWebShop/bootstrap-shortcodes/commit/c26659ccb6ddb871c7dee1b77cb81cad63e7a75b","https://wordpress.org/plugins/bootstrap-shortcodes/#developers","https://github.com/TheWebShop/bootstrap-shortcodes/releases/tag/3.4.6","https://plugins.trac.wordpress.org/browser/bootstrap-shortcodes/tags/3.4.4/inc/bs_tabs.php#L84","https://wordpress.org/plugins/bootstrap-shortcodes/"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:10:43.281Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/112xxx/CVE-2026-112111.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-112111","state":"PUBLISHED","datePublished":"2026-10-18T22:39:46.933Z","dateUpdated":"2026-10-19T16:20:39.966Z","assignerShortName":"mitre","assignerOrgId":"8254265b-2729-46b6-b9e3-3dfca2d5bfca","dateReserved":"2026-10-18T22:39:46.301Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"The Bootstrap Shortcodes plugin for WordPress before 3.4.6 is vulnerable to stored XSS via the id attribute of the [bs_tcontent] shortcode.
