Summary
CWE-470 (Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') when having Javers selected as Entity Audit Framework
Details
In the following two occurences, user input directly leads to class loading without checking against e.g. a whitelist of allowed classes. This is also known as CWE-470 https://github.com/jhipster/generator-jhipster-entity-audit/blob/e21e83135d10c77d92203c89cb0b0063914e8fe0/generators/spring-boot-javers/templates/src/main/java/_package_/web/rest/JaversEntityAuditResource.java.ejs#L88 https://github.com/jhipster/generator-jhipster-entity-audit/blob/e21e83135d10c77d92203c89cb0b0063914e8fe0/generators/spring-boot-javers/templates/src/main/java/_package_/web/rest/JaversEntityAuditResource.java.ejs#L124
So, if an attacker manages to place some malicious classes into the classpath and also has access to these REST interface for calling the mentioned REST endpoints, using these lines of code can lead to unintended remote code execution.
PoC
- Place an arbitrary class with the right package name (starting with JHIpster applications path name) and make it available in class path
- Gain access to view entity's audit changelogs (Role: ADMIN)
- pass in the malicious class name part as
entityType(first mentioned part) //qualifiedName(second mentioned occurence) - class gets loaded and static code blocks in there get executed
--> Should be limited to the already existing whitelist of classes (see first method in that mentioned class)
Impact
Remote Code execution. You need to have some access to place malicious classes into the class path and you need to have a user with ADMIN role on the system.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for generator-jhipster-entity-audit, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update generator-jhipster-entity-audit to 5.9.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-31119 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
