## What is CVE-2020-4100?

CVE-2020-4100 is a medium-severity code injection vulnerability in "HCL Verse for Android", published on 15 Jul 2020. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

"HCL Verse for Android was found to employ dynamic code loading. This mechanism allows a developer to specify which components of the application should not be loaded by default when the application is started. Typically, core components and additional dependencies are loaded natively at runtime; however, dynamically loaded components are only loaded as they are specifically requested. While this can have a positive impact on performance, or grant additional functionality (for example, a non-invasive update feature), it can also open the application to loading unintended code if not implemented properly."

Weakness: CWE-913 (Improper Control of Dynamically-Managed Code Resources)

What it is: CVE-2020-4100 is a medium-severity code injection vulnerability in "HCL Verse for Android", published on 15 Jul 2020. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2020-4100 in the wild and no public exploit code.

Affected product: "HCL Verse for Android". No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
