+title: hammer_cli - Insecure interpolation of the $EDITOR environment variable
+date: 2026-10-01
+description: |
+  A flaw was found in rubygem-hammer_cli. A command injection vulnerability
+  exists in Hammer CLI and the Railties (Ruby on Rails) component
+  distributed with Satellite due to the insecure interpolation of the
+  $EDITOR environment variable into the Ruby system() method.
+  By passing a single interpolated string to system(), the application
+  invokes a system shell (/bin/sh) that interprets shell
+  metacharacters (e.g., ;, |, &).
