### Official description

The Rockwell Automation Enhanced HIM software contains 

an API that the application uses that is not protected sufficiently and uses incorrect Cross-Origin Resource Sharing (CORS) settings and, as a result, is vulnerable to a Cross Site Request Forgery (CSRF) attack. To exploit this vulnerability, a malicious user would have to convince a user to click on an untrusted link through a social engineering attack or successfully perform a Cross Site Scripting Attack (XSS). Exploitation of a CSRF could potentially lead to sensitive information disclosure and full remote access to the affected products.

Weakness: CWE-352 (Cross-Site Request Forgery)

What it is: CVE-2023-2746 is a critical vulnerability in Rockwell Automation Enhanced HIM, published on 11 Jul 2023. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2023-2746 in the wild and no public exploit code.

Affected product: Rockwell Automation Enhanced HIM. 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.
