## Description

Concrete CMS versions 9 through 9.3.2 and below 8.5.18 are vulnerable to Stored XSS in getAttributeSetName(). A rogue administrator could inject malicious code. The Concrete CMS team gave this a CVSS v4.0 rank of 4.6 with vector https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:H/AT:N/PR:H/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N. Thanks, m3dium for reporting. (CNA updated this risk rank on 20 Jan 2025 by lowering the AC based on CVSS 4.0 documentation that access privileges should not be considered for AC)
