Attack profile from CVSS 4.0 · CNA. Fix status from CNA. Impact type from CWE-89.

Summary

Tabularis from 0.10.0 before 0.28.0 contains an SQL injection flaw in its SQLite driver (CWE-89). A crafted table_name passed to the describe_table tool through MCP can close the quoted PRAGMA argument and append statements. An attacker who can reach an MCP client, including an AI agent steered by untrusted content, needs user interaction to trigger it and can read, modify or drop SQLite data while bypassing read-only mode and write approval.

Tabularis before 0.28.0 contains an SQL injection vulnerability in its SQLite driver that allows MCP clients to execute stacked statements by supplying a crafted table_name to the describe_table tool. Attackers, including AI agents steered by untrusted content, can close the quoted PRAGMA argument and append statements to read, modify, or drop SQLite data, bypassing read-only mode and write approval.
