This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitability depends on a consuming plugin or theme built on Meta Box that exposes the background field to lower-privileged users and renders stored values via the rwmb_the_value()/format_single_value() pattern; the effective minimum privilege is whatever role that consumer permits, demonstrated at Subscriber level."}],"title":"Meta Box <= 5.15.2 - Authenticated (Subscriber+) Stored Cross-Site Scripting via Background Field Array Keys","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/7a8948f5-8bcf-48f2-b3a6-bfa24ba9bef0?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/meta-box/tags/5.15.2/inc/fields/background.php#L154"},{"url":"https://plugins.trac.wordpress.org/browser/meta-box/tags/5.15.2/inc/sanitizer.php#L170"},{"url":"https://github.com/wpmetabox/meta-box/pull/1709"},{"url":"https://plugins.trac.wordpress.org/browser/meta-box/tags/5.15.3/inc/fields/background.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:N","baseScore":4.9,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Md.
