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
htags in GNU Global through 6.6.12 allows code execution in situations where dbpath (aka -d) is untrusted, because shell metacharacters may be used.

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

The htags component in GNU Global through 6.6.12 suffers from a command injection vulnerability. When the dbpath parameter (-d) is populated with untrusted input, shell metacharacters are not sanitized before being passed to a shell command, allowing arbitrary code execution.

MitigationEnsure dbpath (-d) input is validated and sanitized before use, or use safe command execution methods that avoid shell interpretation (e.g., execve with explicit arguments instead of system/popen).

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 GNU Global/htags is installed
    Run 'gtags --version' or 'htags --version' to determine installed version
    Affected if Version is 6.6.12 or earlier (vulnerable release range)
  2. Identify htags usage with -d parameter
    Search scripts, configs, or automation that invoke htags with the -d flag (e.g., 'htags -d $USER_INPUT')
    Affected if htags is invoked with a -d argument that accepts external/untrusted input
  3. Check for unsafe command execution
    Inspect source code or wrapper scripts that call htags; look for system(), popen(), or shell=True patterns that pass the dbpath argument
    Affected if Shell interpretation is used (system/popen) rather than execve with explicit arguments
  4. Audit input source for -d parameter
    Trace where the dbpath value originates - if from user input, HTTP parameters, files, or environment variables without validation
    Affected if The -d value is derived from untrusted sources without sanitization of shell metacharacters

A user is affected if GNU Global version is 6.6.12 or earlier AND htags is being run with a -d parameter that accepts untrusted input through unsafe shell execution.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Ensure dbpath (-d) input is validated and sanitized before use, or use safe command execution methods that avoid shell interpretation (e.g., execve with explicit arguments instead of system/popen).

Recommended fix Moderate confidence

GNU Global version greater than 6.6.12 (check official GNU Savannah for latest stable release)

  1. 1. Check the current version of GNU Global installed: `global --version`
  2. 2. Identify the latest stable release of GNU Global from the official GNU Savannah repository at https://www.gnu.org/software/global/
  3. 3. Download and install the latest version (after 6.6.12) that addresses the code injection vulnerability in htags via the -d/dbpath parameter
  4. 4. Verify the new version is installed: `global --version`
  5. 5. Test that shell metacharacters in the -d parameter are now properly sanitized or rejected
Caveat Review release notes for any compatibility changes between 6.6.12 and the new version
