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
Cryptomator through 1.6.5 allows DYLIB injection because, although it has the flag 0x1000 for Hardened Runtime, it has the com.apple.security.cs.disable-library-validation and com.apple.security.cs.allow-dyld-environment-variables entitlements. An attacker can exploit this by creating a malicious .dylib file that can be executed via the DYLD_INSERT_LIBRARIES environment variable.

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

Cryptomator through 1.6.5 has insecure entitlements that enable dylib injection. Although Hardened Runtime is enabled (flag 0x1000), the combination of com.apple.security.cs.disable-library-validation and com.apple.security.cs.allow-dyld-environment-variables entitlements allows attackers to inject malicious .dylib files via the DYLD_INSERT_LIBRARIES environment variable.

MitigationRemove the com.apple.security.cs.disable-library-validation and com.apple.security.cs.allow-dyld-environment-variables entitlements from the application's entitlements file and rebuild the application, or upgrade to version 1.7.0 or later where these insecure entitlements have been removed.

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. Confirm Cryptomator is installed
    Search for Cryptomator in /Applications folder, or run: mdfind kMDItemCFBundleIdentifier == 'org.cryptomator.desktop' or ls /Applications | grep -i cryptomator
    Affected if Cryptomator is found on the system
  2. Determine installed Cryptomator version
    Run: defaults read /Applications/Cryptomator.app/Contents/Info.plist CFBundleShortVersionString, or right-click Cryptomator.app > Get Info > Version
    Affected if Version is 1.6.5 or lower
  3. Locate the entitlements file
    The entitlements file is located at: /Applications/Cryptomator.app/Contents/CodeResources (for packaged app) or check the source if building from source. The file is typically named Cryptomator.entitlements in the project.
    Affected if Entitlements file exists
  4. Inspect entitlements for vulnerable keys
    Open the entitlements file and search for: com.apple.security.cs.disable-library-validation and com.apple.security.cs.allow-dyld-environment-variables. If using plist format, run: defaults read /path/to/Cryptomator.entitlements com.apple.security.cs.disable-library-validation
    Affected if Either com.apple.security.cs.disable-library-validation or com.apple.security.cs.allow-dyld-environment-variables is present and set to true

A user is affected if Cryptomator version 1.6.5 or lower is installed AND the application's entitlements file contains either the com.apple.security.cs.disable-library-validation or com.apple.security.cs.allow-dyld-environment-variables entitlement.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Upgrade available Upgrade to a release after 1.6.5
Interim mitigation

Remove the com.apple.security.cs.disable-library-validation and com.apple.security.cs.allow-dyld-environment-variables entitlements from the application's entitlements file and rebuild the application, or upgrade to version 1.7.0 or later where these insecure entitlements have been removed.
