| Doc Text: |
A flaw was found in TimescaleDB, a time-series database extension for PostgreSQL. A malicious user can exploit this vulnerability by creating functions in user-writable schemas that shadow built-in PostgreSQL functions. During an extension upgrade, PostgreSQL's `search_path` setting, which determines how database objects are located, can cause these malicious functions to be executed instead of the legitimate ones. This can lead to arbitrary code execution, allowing the attacker to run unauthorized commands on the system.
