Summary
ThingLinks is an enterprise IoT platform. Prior to 1.4.0, an unauthenticated SQL injection vulnerability in the `TDengine TDS APIs` allows request-controlled JSON field values submitted to `/anyUser/tds/insertTableData` to reach unsafe SQL construction in the `TDS mapper`. A remote unauthenticated attacker can tamper with TDengine time-series data, including inserting unintended rows or overwriting existing readings. The affected surface is the TDS module's insert-table-data flow and TDengine mapper SQL generation. This issue is fixed in version 1.4.0.
