### Official description

Interpretation conflict in WinSCP before 4.0.4 allows remote attackers to perform arbitrary file transfers with a remote server via file-transfer commands in the final portion of a (1) scp, and possibly a (2) sftp or (3) ftp, URL, as demonstrated by a URL specifying login to the remote server with a username of scp, which is interpreted as an HTTP scheme name by the protocol handler in a web browser, but is interpreted as a username by WinSCP.  NOTE: this is related to an incomplete fix for CVE-2006-3015.

Weakness: CWE-264

Check this codebase for CVE-2007-4909 and fix it if it is affected.

What it is: CVE-2007-4909 is a critical vulnerability in n/a, published on 17 Sep 2007. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2007-4909 exists.

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.
