CVE-2025-71360
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 0.0.29 fails to detect malicious pickle files using idlelib.calltip.get_entity function in reduce methods. Attackers can embed undetected code in pickle files that executes remote commands when loaded by victims.
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 0.0.29 fails to detect malicious pickle files that use the idlelib.calltip.get_entity function within __reduce__ methods. Attackers can exploit this detection bypass to embed malicious code in pickle files that executes remote commands when loaded by victims.

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 Python environmentAffected if picklescan is not installed means this specific CVE does not apply (the tool itself is the vulnerable product)
-
Determine installed picklescan versionRun `pip show picklescan` and note the Version field, or use `pip list` to see the version numberAffected if The version displayed is before 0.0.29 (e.g., 0.0.28, 0.0.27, etc.)
-
Compare version to the fixed releaseManually compare your installed version number to 0.0.29 - versions 0.0.28 and earlier are affected, 0.0.29 and later are fixedAffected if Your installed version is lower than 0.0.29
-
Verify detection bypass (optional validation)Create a test pickle file using `idlelib.calltip.get_entity` in a `__reduce__` method, then scan it with picklescan using its CLI (e.g., `picklescan path/to/file.pkl`)Affected if picklescan reports the file as safe when it should be flagged - this confirms the bypass is present
You are affected if picklescan is installed and its version is lower than 0.0.29, meaning the scanner fails to detect malicious pickles using the idlelib.calltip.get_entity function in __reduce__ methods.
Generated from the published advisory. Verify against your own configuration.
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 0.0.29 or later to remediate this vulnerability. Additionally, avoid loading untrusted pickle files regardless of scanner results as a defense-in-depth measure.
0.0.29
- Check the current installed version of picklescan using: pip show picklescan or pip list | grep picklescan
- Upgrade picklescan to version 0.0.29 or later using: pip install picklescan>=0.0.29
- Verify the upgrade was successful by checking the installed version again
