Impacted is confidentiality, integrity, and availability. CVE summarizes:
The Square Squash allows remote attackers to execute arbitrary code via a YAML document in the (1) namespace parameter to the deobfuscation function or (2) sourcemap parameter to the sourcemap function in app/controllers/api/v1_controller.rb.
