CVE-2026-93349: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in frictionlessdata frictionless-py
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.
AI Analysis
Technical Summary
CVE-2026-93349 describes an OS command injection vulnerability in frictionlessdata's frictionless-py package through version 5.20.0rc1. The vulnerability exists in the explore console command, where an attacker can craft a Data Package descriptor (datapackage.json) containing shell metacharacters in resource path values. These values are passed without sanitization to os.system via a shell, allowing arbitrary command execution as the user running the command. This issue enables an attacker to execute OS commands remotely by tricking a user into exploring a malicious package.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary operating system commands with the privileges of the user running the explore command. This can lead to unauthorized system access, data manipulation, or further compromise depending on the user's permissions. The vulnerability has a high severity score (CVSS 8.6) indicating significant risk if exploited.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid running the explore command on untrusted or unauthenticated Data Package descriptors to prevent exploitation.
