Technical Description

Concrete CMS versions 9.0.0 through 9.3.3 are affected by a

stored XSS vulnerability in the "Top Navigator Bar" block.

with vector CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N . This

does not affect versions below 9.0.0 since they do not have the Top

Navigator Bar Block. Thanks, Chu Quoc Khanh for reporting.
