CVE-2026-62849 Details
Description
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.
A critical unauthenticated SQL injection vulnerability has been identified in ThingLinks versions prior to 1.4.0, specifically within the TDengine TDS APIs. The vulnerability allows remote attackers to manipulate time-series data by injecting malicious JSON field values into the '/anyUser/tds/insertTableData' endpoint. This unsanitized input is then used to construct SQL queries in the TDS mapper, potentially leading to unauthorized data modifications such as inserting false records or overwriting existing data.
Users can upgrade to ThingLinks version 1.4.0 or later, where this vulnerability has been patched. Instructions for updating can be found in the ThingLinks repository on GitHub.
