Deeper analysis
CrafterCMS Engine contains a reflected cross-site scripting vulnerability arising from improper neutralization of input during web page generation. The flaw affects CrafterCMS versions 4.0.0 through 4.0.2 and 3.1.0 through 3.1.27 running on Windows, macOS, Linux, and both x86 and ARM 64-bit platforms, and is tracked as CWE-79 with a CVSS 3.1 score of 7.4.
An unauthenticated remote attacker can supply a crafted request that is reflected back to a victim user, executing arbitrary script in the context of the CrafterCMS site.
