How to Fix CVE-2025-7962

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

org.eclipse.angus:smtp fixed: 2.0.4 
<dependency>
    <groupId>org.eclipse.angus</groupId>
    <artifactId>smtp</artifactId>
    <version>2.0.4</version>
</dependency>
com.sun.mail:jakarta.mail fixed: 1.6.8 
<dependency>
    <groupId>com.sun.mail</groupId>
    <artifactId>jakarta.mail</artifactId>
    <version>1.6.8</version>
</dependency>
com.sun.mail:jakarta.mail fixed: 2.0.2 
<dependency>
    <groupId>com.sun.mail</groupId>
    <artifactId>jakarta.mail</artifactId>
    <version>2.0.2</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=org.eclipse.angus

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2025-7962, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.eclipse.angus

Analyze the terminal output to locate any version of Smtp in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.4), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.eclipse.angus 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-147: Improper Neutralization of Input Terminators, where the product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as input terminators when they are sent to a downstream component. In Smtp, 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

In Jakarta Mail 2.2 it is possible to preform a SMTP Injection by utilizing the \r and \n UTF-8 characters to separate different messages.
