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.\n\n## Affected\n\n- `bootstrap-shortcodes < 3.4.6`\n\n## Remediation\n\nUpdate the Bootstrap Shortcodes plugin to version 3.4.6 or later.\n\n### Workarounds\n\nUntil updated, deactivate the plugin or do not allow untrusted Contributor/Author-level users to publish content containing the [bs_tcontent] shortcode.","depth":"sunlit","depthScore":28,"depthScoreParts":{"impact":28.1,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
