How to Fix CVE-2025-68704

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

net.gleske:jervis fixed: 2.2 
<dependency>
    <groupId>net.gleske</groupId>
    <artifactId>jervis</artifactId>
    <version>2.2</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=net.gleske

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2025-68704, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=net.gleske

Analyze the terminal output to locate any version of Jervis in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=net.gleske 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-330: Use of Insufficiently Random Values, where the product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers. In Jervis, 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

### Vulnerability https://github.com/samrocketman/jervis/blob/157d2b63ffa5c4bb1d8ee2254950fd2231de2b05/src/main/groovy/net/gleske/jervis/tools/SecurityIO.groovy#L593-L594 Uses `java.util.Random()` which is not cryptographically secure. ### Impact If an attacker can predict the random delays, they may still be able to perform timing attacks. ### Patches Jervis will use `SecureRandom` for timing randomization. Upgrade to Jervis 2.2. ### Workarounds None ### References - [OWASP Cryptographic Failures](https://owasp.org/Top10/A02_2021-Cryptographic_Failures/)
