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
An issue was found in Git before v2.24.1, v2.23.1, v2.22.2, v2.21.1, v2.20.2, v2.19.3, v2.18.2, v2.17.3, v2.16.6, v2.15.4, and v2.14.6. Recursive clones are currently affected by a vulnerability that is caused by too-lax validation of submodule names, allowing very targeted attacks via remote code execution in recursive clones.

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

Git before the listed versions contains a vulnerability in recursive clone operations where submodule names are insufficiently validated, allowing attackers to inject malicious paths or commands that execute during the clone process.

MitigationUpdate Git installations to version v2.24.1, v2.23.1, v2.22.2, v2.21.1, v2.20.2, v2.19.3, v2.18.2, v2.17.3, v2.16.6, v2.15.4, or v2.14.6 or later to patch the submodule validation flaw.

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. Determine installed Git version
    Run 'git --version' on the command line and note the version number (e.g., output like 'git version 2.19.0')
    Affected if The version falls within any of these ranges: >= 2.14.0 and < 2.14.6; >= 2.15.0 and < 2.15.4; >= 2.16.0 and < 2.16.6; >= 2.17.0 and < 2.17.3; >= 2.18.0 and < 2.18.2; >= 2.19.0 and < 2.19.3; >= 2.20.0 and < 2.20.2; >= 2.22.0 and < 2.22.2; or is exactly 2.21.0, 2.23.0, or 2.24.0
  2. Identify use of recursive clone with submodules
    Review git operations performed, specifically look for use of 'git clone --recurse-submodules' or 'git submodule update --init --recursive' commands in your workflows
    Affected if These recursive submodule operations are used with repositories or submodules from untrusted sources
  3. Check for custom submodule configurations
    Examine .gitmodules files in repositories you clone, looking for non-standard or unexpected submodule entries
    Affected if Submodule URLs point to unexpected locations or paths that could be controlled by an attacker

You are affected if your installed Git version is one of the vulnerable versions listed AND you perform recursive clone operations on repositories containing submodules, particularly from untrusted sources.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

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.
