Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly requires timely remediation of known software flaws like this RCE vulnerability by applying the vendor patch in D-Tale version 3.20.0.

SI-10 Information Input Validation good match

prevent

Enforces validation of all information inputs to endpoints such as /save-column-filter, preventing improper neutralization that enables RCE.

SC-14 Public Access Protections good match

prevent

Provides protections for publicly accessible interfaces like the vulnerable D-Tale endpoint, rejecting unauthorized access or enforcing controls on public exposure.

Deeper analysisAI

CVE-2026-27194 is a remote code execution vulnerability affecting D-Tale, a visualizer for pandas data structures, in versions prior to 3.20.0. The flaw exists in the /save-column-filter endpoint, which allows attackers to execute arbitrary code on the server. Published on 2026-02-21, it carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-74 (Improper Neutralization of Special Elements used in an SQL Command).

Any unauthenticated attacker with network access to a publicly hosted D-Tale instance can exploit this vulnerability without user interaction or privileges. Successful exploitation enables remote code execution, granting high-impact access to confidentiality, integrity, and availability on the affected server by running malicious code.

The issue has been addressed in D-Tale version 3.20.0. The GitHub security advisory (GHSA-c87c-78rc-vmv2) and fixing commit (431c6148d3c799de20e1dec86c4432f48e3d0746) detail the patch, recommending immediate upgrades for exposed deployments.
