# CVE-2026-93349: Frictionless OS Command Injection via explore Console Command

Status: published. Published: 2026-09-23. Updated: 2026-11-08.

Frictionless before 5.19.1 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. This vulnerability was also addressed in version 5.20.0rc2 of the pre-release branch.
