What is CVE-2026-50006?
CVE-2026-50006 is a critical path traversal vulnerability in julien040 anyquery, published on 14 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Anyquery is an SQL query engine built on top of SQLite. Prior to 0.4.5, anyquery server forwards unauthenticated SQL from its MySQL-compatible server port to SQLite without restricting ATTACH DATABASE filesystem targets. A remote attacker can select any path writable by the Anyquery server process, cause SQLite to create a database file there, and place attacker-controlled table content in that file. This permits arbitrary file creation or overwrite, causing filesystem integrity loss and denial of service; remote code execution is possible only when another service interprets the written file or the process has a suitably privileged writable target. This issue is fixed in version 0.4.5.
