CVE-2025-71367
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 0.0.34 fails to detect _operator.attrgetter function calls in pickle payloads, allowing attackers to bypass security checks. Remote attackers can craft malicious pickle files using _operator.attrgetter in reduce methods to execute arbitrary code when pickle.load() processes the file.
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 0.0.34 fails to detect _operator.attrgetter function calls embedded in pickle payload reduce methods. This allows malicious pickle files to bypass the security scanner and execute arbitrary code when unpickled, as _operator.attrgetter can be weaponized to access sensitive attributes and trigger code execution.

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.
-
Identify picklescan installationRun 'pip show picklescan' or check your project's dependencies (requirements.txt, package-lock.json, pyproject.toml) for the picklescan packageAffected if picklescan is installed in your environment
-
Determine installed picklescan versionRun 'pip show picklescan' and note the Version field, or check your lock file for the installed version numberAffected if The installed version is earlier than 0.0.34 (e.g., 0.0.33, 0.0.30, etc.)
-
Verify if picklescan scans untrusted pickle filesReview your code, scripts, or CI/CD pipelines that invoke picklescan to scan pickle files from external or untrusted sourcesAffected if picklescan is used to validate pickle files from untrusted sources
You are affected if picklescan version 0.0.33 or earlier is installed and used to scan pickle files from untrusted sources, as the scanner can be bypassed using _operator.attrgetter 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 0.0.34 or later which includes detection for _operator.attrgetter. As a defense-in-depth measure, avoid using pickle.load() on untrusted data entirely and prefer safer serialization formats.
picklescan 0.0.34
- Check the currently installed version of picklescan: pip show picklescan or picklescan --version
- Upgrade picklescan to version 0.0.34 or later: pip install picklescan>=0.0.34
- Verify the upgrade was successful by checking the version: pip show picklescan
