CVE-2025-71354
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 that exploit idlelib.debugobj.ObjectTreeItem.SetText function in reduce methods. Attackers can craft pickle files with embedded code that bypasses picklescan detection and executes arbitrary commands when pickle.load() is called.
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 exploit the idlelib.debugobj.ObjectTreeItem.SetText function within __reduce__ methods, allowing attackers to craft payloads that bypass the scanner's detection and execute arbitrary commands when pickle.load() is called.

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 the Python environmentAffected if picklescan is installed and being used to scan pickle files
-
Determine the installed versionRun 'pip show picklescan' and look for the Version field, or use 'pip freeze | grep picklescan' to get the exact version numberAffected if The version displayed is lower than 0.0.29 (e.g., 0.0.28, 0.0.27, etc.)
-
Verify picklescan is actively used in the workflowInspect scripts, CI/CD pipelines, or code that invokes picklescan to scan pickle files from external or untrusted sourcesAffected if picklescan is used as part of a security scanning pipeline for pickle files
-
Check for recent scan activity or logsReview any picklescan scan logs, reports, or output files to confirm pickle files have been scannedAffected if picklescan has been used to scan pickle files, particularly those from external or untrusted sources
You are affected if picklescan version 0.0.28 or earlier is installed and has been used to scan pickle files, as malicious files exploiting idlelib.debugobj.ObjectTreeItem.SetText within __reduce__ methods would bypass detection.
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 the detection bypass, and avoid loading pickle files from untrusted sources regardless of scanner results.
picklescan 0.0.29
- Upgrade picklescan to version 0.0.29 or later using pip: pip install picklescan>=0.0.29
- Verify the installed version: pip show picklescan
