How to Fix CVE-2026-54704

To remediate this vulnerability, upgrade all affected OpenTelemetry Java Instrumentation dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

io.opentelemetry.javaagent:opentelemetry-javaagent fixed: 2.28.0-alpha 
<dependency>
    <groupId>io.opentelemetry.javaagent</groupId>
    <artifactId>opentelemetry-javaagent</artifactId>
    <version>2.28.0-alpha</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=io.opentelemetry.javaagent

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-54704, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.opentelemetry.javaagent

Analyze the terminal output to locate any version of OpenTelemetry Java Instrumentation in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.28.0-alpha), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.opentelemetry.javaagent command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-532: Insertion of Sensitive Information into Log File, where the product writes sensitive information to a log file. In OpenTelemetry Java Instrumentation, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

OpenTelemetry Java Instrumentation JDBC auto-instrumentation may fail to sanitize passwords in SQL CONNECT statements when the password is double-quoted. As a result, clear-text database passwords can be added to trace span attributes and exported to observability backends.
