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
Perl module Data::UUID from CPAN version 1.219 vulnerable to symlink attacks

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 Data::UUID Perl module version 1.219 from CPAN contains a symlink attack vulnerability, likely in its handling of temporary file creation or file operations where the application may follow symbolic links created by attackers to overwrite or access unintended files.

MitigationUpgrade Data::UUID to a patched version newer than 1.219, or ensure strict permissions and validation on directories used for temporary file operations to prevent symlink-based file manipulation.

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 Data::UUID Perl module version
    Run: perl -MData::UUID -e 'print $Data::UUID::VERSION'
    Affected if The version reported is less than 1.224 (e.g., 1.219 or earlier)
  2. Check Debian system package version
    Run: dpkg -l libdata-uuid-perl and examine the version field
    Affected if The installed package version is lower than 1.224-1 (check your distribution's package index for the exact version mapping)

A user is affected if they have Data::UUID module version 1.219 or any version prior to 1.224 installed, as these versions contain the symlink attack flaw in temporary file handling.

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.

AI-assisted, checked against the advisory. Informational, not a guarantee.

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 1.224 or later

Interim mitigation

Upgrade Data::UUID to a patched version newer than 1.219, or ensure strict permissions and validation on directories used for temporary file operations to prevent symlink-based file manipulation.
