CVE-2026-31233: n/a
Guardrails AI thru 0.6.7 contains a code injection vulnerability (CWE-94) in its Hub package installation mechanism. When installing validator packages via guardrails hub install, the system retrieves a manifest from the Guardrails Hub and dynamically executes a script specified in the post_install field. The script path is constructed from untrusted manifest data and executed without proper validation or sanitization, allowing remote code execution. An attacker who can publish malicious packages to the Hub can inject arbitrary code that will be executed on any system where a victim installs the malicious package.
AI Analysis
Technical Summary
CVE-2026-31233 is a critical code injection vulnerability in Guardrails AI (up to version 0.6.7) affecting the Hub package installation process. When installing validator packages via 'guardrails hub install', the system downloads a manifest from the Guardrails Hub that includes a post_install script path. This path is constructed from untrusted manifest data and executed dynamically without validation or sanitization, enabling remote code execution. An attacker capable of publishing malicious packages to the Hub can exploit this to run arbitrary code on victim systems during package installation. The vulnerability has a CVSS 3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). There is no known exploit in the wild and no vendor advisory or patch information is currently available.
Potential Impact
Successful exploitation allows remote code execution with no privileges required and no user interaction, resulting in full confidentiality, integrity, and availability compromise of affected systems. An attacker publishing malicious packages to the Guardrails Hub can execute arbitrary code on any system installing those packages, potentially leading to complete system takeover.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid installing packages from untrusted sources on the Guardrails Hub. Monitor for updates from the Guardrails AI vendor regarding patches or mitigations.
