Description (CNA)
Concrete CMS versions 9.0.0 to 9.3.2 and below 8.5.18 are vulnerable to Stored XSS in RSS Displayer when user input is stored and later embedded into responses. A rogue administrator could inject malicious code into fields due to insufficient input validation. The Concrete CMS security team gave this vulnerability a CVSS v4 score of 5.1 with vector https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:H/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N Thanks, m3dium for reporting. (CNA updated this risk rank on 17 Jan 2025 by lowering the AC based on CVSS 4.0 documentation that access privileges should not be considered for AC)
