CVE-2026-27194 has a CVSS 3.1 base score of 9.8 (Critical). CVSS vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. EPSS exploitation probability: 0.4%.

How to fix or mitigate CVE-2026-27194?

Within 24 hours: Inventory all systems running D-Tale and identify version numbers; isolate or disable D-Tale instances if patching cannot be completed immediately. Within 7 days: Apply vendor patch to upgrade all D-Tale installations to version 3.20.0 or later, and verify successful deployment in non-production environments first. Within 30 days: Conduct security audit of affected systems for indicators of compromise, review access logs for suspicious /save-column-filter endpoint activity, and implement network monitoring for D-Tale endpoints.

CRITICAL 9.8

DescriptionGitHub Advisory

D-Tale is a visualizer for pandas data structures. Versions prior to 3.20.0 are vulnerable to Remote Code Execution through the /save-column-filter endpoint. Users hosting D-Tale publicly can be vulnerable to remote code execution allowing attackers to run malicious code on the server. This issue has been fixed in version 3.20.0.

Executive ViewAI

Why It Matters

A critical remote code execution vulnerability in D-Tale (versions before 3.20.0) allows unauthenticated attackers to execute arbitrary code on systems running affected versions. Organizations using D-Tale for data visualization must immediately patch or disable the application to prevent potential data theft, system compromise, and operational disruption.

Business Impact: Severe

Compensating Controls

Apply vendor patch. If immediate patching is not feasible: (1) Restrict network access to D-Tale instances using firewall rules or network segmentation, limiting to trusted internal IPs only; (2) Implement WAF rules to block POST requests to the /save-column-filter endpoint; (3) Disable D-Tale if not actively required; (4) Run D-Tale in a sandboxed or containerized environment to limit lateral movement from compromise.
