What it is

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.
