CVE-2026-62350Public exploitNetwork attack vector

Authenticated code execution via unvalidated UDF libraries

Published Jul 15, 2026 · Updated Jul 15, 2026

Code injection in TAOS Data TDengine before 3.4.1.15 allows remote authenticated users to execute arbitrary C code on the server. The UDF creation path accepts an uploaded shared library from a user holding create udf and loads it as server-side query code without validating its behavior. The create udf privilege is required; after installing a crafted function, database queries can invoke code with the taosd process's privileges.
