Critical CVSS 9.3

An unauthenticated remote code execution vulnerability exists in Remote for Mac, a macOS remote control utility developed by Aexol Studio, in versions up to and including 2025.7. When the application is configured with authentication disabled (i.e., the "Allow unknown devices" option is enabled), the /api/executeScript endpoint is exposed without access control. This allows unauthenticated remote attackers to inject arbitrary AppleScript payloads via the X-Script HTTP header, resulting in code execution using do shell script. Successful exploitation grants attackers the ability to run arbitrary commands on the macOS host with the privileges of the Remote for Mac background process.

Matched remediation archetype

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
