This makes it possible for authenticated attackers, with Administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.","cvssScore":4.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/hostel/tags/1.1.6/helpers/htmlhelper.php#L275","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/hostel/tags/1.1.6/helpers/htmlhelper.php#L278","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/hostel/tags/1.1.6/models/hostel.php#L266","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/hostel/tags/1.1.6/views/options.php#L17","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/75693bd1-f022-47b9-b498-5ea1bda387e3?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
