### Official description

A remote file include (RFI) issue was discovered in Enghouse Web Chat 6.2.284.34. One can replace the localhost attribute with one's own domain name. When the product calls this domain after the POST request is sent, it retrieves an attacker's data and displays it. Also worth mentioning is the amount of information sent in the request from this product to the attacker: it reveals information the public should not have. This includes pathnames and internal ip addresses.

Weakness: CWE-829 (Inclusion of Functionality from Untrusted Control Sphere)

Check this codebase for CVE-2019-16951 and fix it if it is affected.

What it is: CVE-2019-16951 is a medium-severity server-side request forgery vulnerability in n/a, published on 13 Nov 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2019-16951 in the wild and no public exploit code.

Affected product: n/a. 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.
