+title: CamaleonCMS 2.9.1 Server-Side Template Injection via test_email Action
+date: 2026-08-12
+description: |
+  CamaleonCMS 2.9.1 contains a server-side template injection vulnerability
+  that allows authenticated administrators to execute arbitrary commands
+  by embedding ERB tags in the email parameter of the test_email settings
+  action, which are evaluated when an SMTP rejection reflects the recipient
+  address back in the exception message rendered as an inline ERB template.
+  Attackers can submit a crafted email parameter containing ERB expressions
+  through the admin settings test_email endpoint, causing the Rails inline
+  template renderer to evaluate attacker-controlled Ruby code and achieve
+  arbitrary command execution as the Rails process user.
