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.

There was an argument injection vulnerability in Sourcetree for macOS from version 1.0b2 before version 3.0.0 via Git subrepositories in Mercurial repositories. An attacker with permission to commit to a Mercurial repository linked in Sourcetree for macOS is able to exploit this issue to gain code execution on the system.

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.

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 Sourcetree for macOS is installed
    Check for the application at /Applications/Sourcetree.app or search using 'mdfind kMDItemFSName == "Sourcetree.app"' in Terminal
    Affected if The application exists in the system
  2. Determine installed Sourcetree version
    Run 'defaults read /Applications/Sourcetree.app/Contents/Info CFBundleShortVersionString' in Terminal to retrieve the version number
    Affected if Version is 1.0b2 or higher but lower than 3.0.0
  3. Verify user works with Mercurial repositories
    Check if any .hg directories exist in user repositories or look for Mercurial repository folders marked with Sourcetree's Hg icon in the application
    Affected if The user has cloned or manages Mercurial repositories using Sourcetree
  4. Inspect Git subrepository configurations
    Look for .gitmodules files within Mercurial repositories in the user's workspace, as the vulnerability exploits maliciously crafted Git subrepository settings
    Affected if .gitmodules files exist within Mercurial repositories and those repositories are managed by the affected Sourcetree version

User is affected if Sourcetree for macOS version 1.0b2 through 2.x is installed and the user manages Mercurial repositories containing Git subrepository configurations.
