# CVE-2026-10105: agno 2.6.5 SQL Injection via ClickHouse delete_by_metadata()

Status: published. Published: 2026-05-29. Updated: 2026-11-08.

agno 2.6.5 contains a SQL injection vulnerability in the ClickHouse vector database backend that allows attackers to inject arbitrary SQL expressions by supplying malicious metadata keys and values to the delete_by_metadata() method. Attackers can exploit the unsafe f-string interpolation in clickhousedb.py to delete all rows, target specific rows, or extract information through error-based or blind SQL injection techniques.
