Security readout for executives and security teams
Plain-English summary
CVE-2022-32852 is an Apple macOS flaw where a malicious AppleScript binary could crash a process or expose process memory. It is fixed in macOS Monterey 12.5. The main business risk is data exposure from endpoints that process untrusted AppleScript content and have not received the Apple fix.
Executive priority
Treat this as a high-priority endpoint patching issue, especially for macOS systems exposed to externally supplied files or sensitive data. It is not listed as known exploited in the provided sources, so urgency should be driven by asset sensitivity, patch age, and exposure to untrusted AppleScript content.
Technical view
This is a CWE-125 out-of-bounds read in macOS AppleScript binary processing. Apple addressed it with improved input validation in macOS Monterey 12.5. CVSS 3.1 is 7.1, with local attack vector, low complexity, no privileges required, required user interaction, high confidentiality impact, and high availability impact.
Likely exposure
Exposure is most likely on Apple macOS systems that process AppleScript binaries and are not updated to macOS Monterey 12.5 or applicable Apple-fixed guidance. The source bundle does not specify exact vulnerable macOS versions beyond an unspecified macOS affected entry and the Monterey 12.5 fix.
Exploitation context
The bundle does not cite active exploitation, and KEV is false. Exploitation requires a maliciously crafted AppleScript binary to be processed locally with user interaction. Sources support potential process termination or process-memory disclosure, not remote unauthenticated network exploitation.
Researcher notes
Evidence is limited to Apple and CVE metadata. The advisory describes improved input validation and impact, but not detailed root cause, proof-of-concept status, affected version range, or detection indicators. Avoid assuming affected Apple products beyond macOS and the stated Monterey 12.5 fix.
Mitigation direction
- Update affected macOS systems to macOS Monterey 12.5 or vendor-applicable fixed releases.
- Check Apple guidance for any platform-specific replacement or superseding security updates.
- Restrict processing of untrusted AppleScript binaries on managed macOS endpoints.
- Use endpoint controls to quarantine or block suspicious script files.
- Prioritize systems handling sensitive data or receiving external files.
Validation and detection
- Inventory macOS assets and record installed OS versions.
- Verify target systems are on Monterey 12.5 or Apple-advised fixed versions.
- Review endpoint policy for AppleScript binary handling and script execution controls.
- Check EDR or crash logs for unusual AppleScript-related process termination.
- Confirm user-facing workflows do not require opening untrusted AppleScript binaries.

Out-of-bounds Read
Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
