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. wp_kses_post does not strip the payload on save because the dangerous characters reside within shortcode attribute text between square brackets, which kses treats as plain text rather than HTML markup.","cvssScore":6.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://avada.com/blog/version-7-16-3-security-update/","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/650d346d-c30a-4ee1-ac50-6a264e181174?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
