## What is CVE-2025-6376?

CVE-2025-6376 is a high-severity memory corruption vulnerability in Rockwell Automation Arena®, published on 9 Jul 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

A remote
code execution security issue exists in the Rockwell Automation Arena®.  A crafted DOE
file can force Arena Simulation to write beyond the boundaries of an allocated
object. Exploitation
requires user interaction, such as opening a malicious file within the software.
If exploited, a threat actor could execute arbitrary code on the target system.
The software must run under the context of the administrator in order to cause
worse case impact. This is reflected in the Rockwell CVSS score, as AT:P.

Weakness: CWE-787 (Out-of-bounds Write), CWE-20 (Improper Input Validation)

Check this codebase for CVE-2025-6376 and fix it if it is affected.

What it is: CVE-2025-6376 is a high-severity memory corruption vulnerability in Rockwell Automation Arena®, published on 9 Jul 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2025-6376 in the wild and no public exploit code.

Affected product: Rockwell Automation Arena®. 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.
