OS Command Injection in Frictionless

Publication date: 2026-09-23

Last updated on: 2026-09-23

Assigner: VulnCheck

Description
Frictionless through 5.20.0rc1 contains an OS command injection vulnerability in the explore console command that allows an attacker who supplies a crafted Data Package descriptor to execute arbitrary operating system commands as the user who explores it. Attackers can place shell metacharacters in resource path values within a datapackage.json descriptor, which are passed unsanitized to os.system through a shell, causing arbitrary command execution in the victim's security context when they run the explore command against the untrusted package.

Executive Summary

This is an OS command injection vulnerability in the Frictionless Python library up to version 5.20.0rc1. Attackers can craft a malicious datapackage.json file with shell metacharacters in resource paths. When a victim runs the explore command on this file, the unsanitized input is passed to os.system via a shell, allowing arbitrary command execution in the victim's security context.

Detection Guidance

To detect this vulnerability, check if Frictionless versions up to and including 5.20.0rc1 are installed. Run `pip show frictionless` to verify the version. If the version is vulnerable, inspect datapackage.json files for resource paths containing shell metacharacters like &, ;, or |.

Impact Analysis

If you use the Frictionless library and run the explore command on untrusted datapackage.json files, an attacker could execute arbitrary commands on your system. This could lead to file access, data theft, local program execution, or disruption of your workflows. The impact depends on your system permissions.

Compliance Impact

This vulnerability could lead to unauthorized data access or exfiltration, violating GDPR's data protection requirements or HIPAA's safeguards for protected health information. Organizations using Frictionless may face compliance violations if exploited, potentially resulting in fines or legal consequences.

Mitigation Strategies

Immediately update Frictionless to a patched version. If updating is not possible, avoid using the explore command on untrusted datapackage.json files. Replace os.system with subprocess.run in the codebase to prevent shell injection.
