CVE-2025-71368
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 · uneditedpicklescan before 0.0.30 fails to detect the doctest.debug_script function when analyzing pickle files, allowing attackers to execute arbitrary code. Remote attackers can craft malicious pickle files embedding doctest.debug_script calls that bypass picklescan detection and execute arbitrary commands upon pickle.load invocation.
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 confidencepicklescan before version 0.0.30 contains an incomplete detection signature set that fails to identify the doctest.debug_script function when scanning pickle files. Attackers can embed calls to doctest.debug_script within malicious pickle files, which will execute arbitrary code when the file is loaded via pickle.load(), bypassing the scanner entirely.

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 checksWork through these to decide whether this CVE applies to you.
-
Check if picklescan is installedRun 'pip show picklescan' or 'pip list | grep picklescan' to see if the package is present in your environmentAffected if picklescan is not installed, the vulnerability does not apply to your environment
-
Determine the installed version of picklescanRun 'pip show picklescan' and note the Version field, or run 'pip list --outdated' to see version informationAffected if The version displayed is below 0.0.30 (for example, 0.0.29, 0.0.28, etc.)
-
Verify picklescan usage in your workflowSearch your codebase or automation scripts for imports of picklescan or calls to pickle scanning functionsAffected if Your pipeline or code uses picklescan to scan pickle files from untrusted sources and the installed version is below 0.0.30
You are affected if picklescan version 0.0.30 or earlier is installed and you rely on it to scan pickle files from potentially untrusted sources.

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.
dbcve · scopedUpgrade picklescan to version 0.0.30 or later to include doctest.debug_script detection. Additionally, avoid loading pickle files from untrusted sources and consider using restricted unpicklers or alternative serialization formats where possible.
picklescan version 0.0.30 or later
- Check current installed version: pip show picklescan or pip list | grep picklescan
- Upgrade picklescan to version 0.0.30 or later: pip install --upgrade picklescan>=0.0.30
- Verify the upgrade was successful by checking the new version: pip show picklescan
- Ensure the new version (0.0.30+) correctly detects doctest.debug_script in pickle files if using picklescan for security scanning
