CVE-2025-26795Network attack vector

Credential disclosure via INFO-level property logging

Published May 14, 2025 · Updated May 19, 2025

Sensitive-information exposure in Apache IoTDB JDBC Driver allows attackers to read JDBC connection credentials from application logs. IoTDBDataSourceFactory.setProperties writes the supplied JDBC URL, username, and password to INFO-level log messages while configuring a data source. Applications using 0.10.0 through 1.3.3 or 2.0.1-beta before 2.0.2 are exposed when attackers can access those logs, disclosing database credentials.
