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
OpenVPN Connect installer for macOS version 3.2.6 and older may corrupt system critical files it should not have access via symlinks in /tmp.

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 · moderate confidence

The OpenVPN Connect installer for macOS versions 3.2.6 and older contains a symlink attack vulnerability in its handling of temporary files in /tmp. The installer follows symbolic links when writing to the world-writable /tmp directory, potentially allowing it to overwrite or corrupt system critical files outside its intended scope.

MitigationUpgrade OpenVPN Connect for macOS to a version newer than 3.2.6. Until upgraded, avoid running the installer with elevated privileges and ensure /tmp directory is not exploitable by untrusted users.

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 if OpenVPN Connect is installed on macOS
    Open Finder, go to /Applications folder, or run: ls /Applications | grep -i openvpn
    Affected if OpenVPN Connect appears in Applications folder or command output
  2. Determine installed OpenVPN Connect version

    Affected if Version number displayed is 3.2.6 or lower
  3. Verify the specific vulnerable version range
    Compare your installed version against the affected range: versions 3.2.6 and older are vulnerable. The exact version is shown in the Get Info window or from the defaults command above.
    Affected if Installed version is 3.2.6 or any version number lower than 3.2.6 (e.g., 3.2.5, 3.2.0, etc.)
