Summary
ThingLinks, an enterprise IoT platform, is affected through its TDengine TDS API insert-table-data flow, which allows unauthenticated remote attackers to inject SQL. This could let an attacker tamper with TDengine time-series data, such as inserting unintended rows or overwriting existing sensor readings.

Read the original 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.

Questions about CVE-2026-62849
What does this mean?
Unsafe SQL construction in the TDS mapper can allow tampering with TDengine time-series data, including inserting unintended rows or overwriting existing readings.Source: github.com
Am I affected, and how do I check?
Affected versions are ThingLinks releases before 1.4.0 that use the TDS module, including its TDengine insert-table-data flow and TDengine mapper SQL generation. To check, look up the installed ThingLinks version and whether the TDS module with TDengine is in use.Source: github.com
What should I do about it?
Upgrade ThingLinks to version 1.4.0, which is the fixed release.Source: github.com
Is it being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
