CVE-2026-62350: CWE-94: Improper Control of Generation of Code ('Code Injection') in taosdata TDengine
TDengine is an open source, time-series database optimized for Internet of Things devices. Prior to 3.4.1.15, a user with create udf privilege could upload a crafted shared library and install it as a user-defined function, such as eval, then execute arbitrary C code on the TDengine server side through database queries. This issue is fixed in version 3.4.1.15.
AI Analysis
Technical Summary
TDengine versions before 3.4.1.15 contain a code injection vulnerability (CWE-94) where users with create udf privilege can upload malicious shared libraries as user-defined functions (e.g., eval). This allows execution of arbitrary C code on the server side via database queries. The vulnerability has a CVSS 3.1 score of 7.2, indicating high impact on confidentiality, integrity, and availability. The flaw is resolved in version 3.4.1.15.
Potential Impact
An attacker with create udf privilege can execute arbitrary C code on the TDengine server, leading to full compromise of the database server's confidentiality, integrity, and availability. This can result in unauthorized data access, data manipulation, or denial of service.
Mitigation Recommendations
Upgrade TDengine to version 3.4.1.15 or later, where this vulnerability is fixed. No other mitigation or temporary workaround is provided in the available data.
