Summary

CVE-2026-40899 is a high-severity Permissive List of Allowed Inputs (CWE-183) vulnerability in Dataease Dataease. Its CVSS base score is 8.3 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 32th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data

DataEase is an open-source data visualization and analytics platform. Versions 2.10.20 and below contain a JDBC parameter blocklist bypass vulnerability in the MySQL datasource configuration. The Mysql class uses Lombok's @Data annotation, which auto-generates a public setter for the illegalParameters…

field that contains the JDBC security blocklist. When a datasource configuration is submitted as JSON, Jackson deserialization calls setIllegalParameters with an attacker-supplied empty list, replacing the blocklist before getJdbc() validation runs. This allows an authenticated attacker to include dangerous JDBC parameters such as allowLoadLocalInfile=true, and by pointing the datasource at a rogue MySQL server, exploit the LOAD DATA LOCAL INFILE protocol feature to read arbitrary files from the DataEase server filesystem, including sensitive environment variables and database credentials. This issue has been fixed in version 2.10.21.

Mitigating Controls (NIST 800-53 r5) AI

Strict validity checks on inputs directly stop overly permissive allow lists from being used as the protection mechanism.

prevents

Secure SDLC practices directly require rigorous allow-list design and testing that prevents permissive input validation.

finds

Security testing can detect overly broad allow-lists, but does not inherently prevent their creation.

prevents

Application security requirements can mandate strict, minimal allow-lists and input validation rules that prevent overly permissive lists.

prevents

Secure system architecture and engineering principles require explicit, least-privilege input validation designs that directly address permissive allow-lists.

prevents

Secure coding standards enforce rigorous input validation and reject unsafe values, mitigating permissive allow-list weaknesses.

none

Configuration management can enforce validated input rules, yet does not directly address the design flaw of permissive lists.
