CVE-2026-86123
SQL Chat contains four unauthenticated API endpoints that accept client-supplied database connection parameters and execute arbitrary SQL queries against attacker-specified hosts.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.33%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
SQL Chat contains four unauthenticated API endpoints that accept client-supplied database connection parameters and execute arbitrary SQL queries against attacker-specified hosts. Attackers can connect to internal databases, execute SQL commands, enumerate schemas, and pivot into the server's network without authentication.
