{"id":"CVE-2026-112111","details":"The Bootstrap Shortcodes plugin for WordPress before 3.4.6 is vulnerable to stored XSS via the id attribute of the [bs_tcontent] shortcode. 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.","modified":"2026-10-19T10:45:14.249045618Z","published":"2026-10-18T22:39:46.933Z","database_specific":{"cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112111.json","cna_assigner":"mitre"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112111.json"},{"type":"PACKAGE","url":"https://github.com/TheWebShop/bootstrap-shortcodes"},{"type":"FIX","url":"https://github.com/TheWebShop/bootstrap-shortcodes/commit/c26659ccb6ddb871c7dee1b77cb81cad63e7a75b"},{"type":"WEB","url":"https://github.com/TheWebShop/bootstrap-shortcodes/releases/tag/3.4.6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-112111"},{"type":"ARTICLE","url":"https://plugins.trac.wordpress.org/browser/bootstrap-shortcodes/tags/3.4.4/inc/bs_tabs.php#L84"},{"type":"WEB","url":"https://wordpress.org/plugins"},{"type":"WEB","url":"https://wordpress.org/plugins/bootstrap-shortcodes/"},{"type":"ADVISORY","url":"https://wordpress.org/plugins/bootstrap-shortcodes/#developers"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/thewebshop/bootstrap-shortcodes","events":[{"introduced":"0"},{"fixed":"4a8875e2b720d7fee6dfed427297e200eaf45f55"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.4.6"}],"source":"AFFECTED_FIELD"}}],"versions":["3.4.4","3.4.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-112111.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
