How to Fix CVE-2026-9370

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

com.github.ulisesbocchio:jasypt-spring-boot fixed: Latest secure release 
<dependency>
    <groupId>com.github.ulisesbocchio</groupId>
    <artifactId>jasypt-spring-boot</artifactId>
    <version>Latest secure release</version>
</dependency>
com.github.ulisesbocchio:jasypt-spring-boot-starter fixed: Latest secure release 
<dependency>
    <groupId>com.github.ulisesbocchio</groupId>
    <artifactId>jasypt-spring-boot-starter</artifactId>
    <version>Latest secure release</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=com.github.ulisesbocchio

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-9370, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.github.ulisesbocchio

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

Note: The mvn dependency:tree -Dincludes=com.github.ulisesbocchio 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-759: Use of a One-Way Hash without a Salt, where the product uses a one-way cryptographic hash against an input that should not be reversible, such as a password, but the product does not also use a salt as part of the input. In Spring Framework, 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

A weakness has been identified in ulisesbocchio jasypt-spring-boot up to 3.0.5/4.0.4. Affected by this vulnerability is the function getSecretKeySaltGenerator of the file jasypt-spring-boot/src/main/java/com/ulisesbocchio/jasyptspringboot/encryptor/SimpleGCMConfig.java of the component Password Hash Handler. Executing a manipulation can lead to use of a one-way hash with a predictable salt. The attack can be launched remotely. The attack requires a high level of complexity. The exploitation appears to be difficult. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
