+title: Insufficient input sanitization in ejson2env
+date: 2025-05-21
+description: |
+  ### Summary
+  The `ejson2env` tool has a vulnerability related to how it writes to
+  `stdout`. Specifically, the tool is intended to write an export
+  statement for environment variables and their values. However, due
+  to inadequate output sanitization, there is a potential risk where
+  variable names or values may include malicious content, resulting
+  in additional unintended commands being output to `stdout`. If this
+  output is improperly utilized in further command execution, it could
+  lead to command injection vulnerabilities, allowing an attacker to
+  execute arbitrary commands on the host system.
+
+  ### Details
+  The vulnerability exists because environment variables are not
+  properly sanitized during the decryption phase, which enables
+  malicious keys or encrypted values to inject commands.
+
+  ### Impact
+  An attacker with control over `.ejson` files can inject commands
+  in the environment where `source $(ejson2env)` or `eval ejson2env`
+  are executed.
+
+  ### Mitigation
+  - Update to a version of `ejson2env` that sanitizes the output
+    during decryption or
+  - Do not use `ejson2env` to decrypt untrusted user secrets or
+  - Do not evaluate or execute the direct output from `ejson2env`
+    without removing nonprintable characters.
