Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Untrusted search path vulnerability in OSA Scripts in Apple OS X before 10.11.3 allows attackers to load arbitrary script libraries via a quarantined application.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

An untrusted search path vulnerability in OSA Scripts (Open Scripting Architecture) in Apple OS X before 10.11.3 allows a quarantined application to load arbitrary script libraries from attacker-controlled locations by exploiting the library search path, potentially leading to arbitrary code execution.

MitigationApply Apple OS X 10.11.3 or later security update to patch the vulnerability. Additionally, exercise caution when running quarantined applications and verify the integrity of script sources.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check the installed OS X version
    Open Apple menu > About This Mac, or run 'sw_vers' in Terminal, and note the version number (e.g., 10.11.2, 10.11.1, 10.11.0)
    Affected if The version is 10.11.2 or lower (10.11.0, 10.11.1, or 10.11.2)
  2. Determine if OSA Scripts functionality is active
    Check if any applications or scripts leverage Open Scripting Architecture (OSA) by reviewing installed applications or looking for .scpt/.applescript files in use
    Affected if OSA Scripts are actively used or available on the system and the OS version is 10.11.2 or lower
  3. Inspect the OSA library search path
    Review the environment variable and configuration for OSA script library paths, typically accessible via osascript command or OSA-related system preferences
    Affected if The search path includes user-writable or untrusted locations and the OS version is 10.11.2 or lower
  4. Identify quarantined applications using OSA
    Check for applications that have been downloaded from the internet (quarantined) and use AppleScript or OSA functionality by examining application bundles or running 'xattr -l' on suspect applications
    Affected if A quarantined application that uses OSA scripts is present and the OS version is 10.11.2 or lower

The environment is affected if the installed OS X version is 10.11.2 or lower and OSA Scripts are in use, allowing a quarantined application to exploit the library search path.
