## What is CVE-2025-50688?

CVE-2025-50688 is a medium-severity command injection vulnerability in n/a, published on 5 Aug 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A command injection vulnerability exists in TwistedWeb (version 14.0.0) due to improper input sanitization in the file upload functionality. An attacker can exploit this vulnerability by sending a specially crafted HTTP PUT request to upload a malicious file (e.g., a reverse shell script). Once uploaded, the attacker can trigger the execution of arbitrary commands on the target system, allowing for remote code execution. This could lead to escalation of privileges depending on the privileges of the web server process. The attack does not require physical access and can be conducted remotely, posing a significant risk to the confidentiality and integrity of the system.

Weakness: CWE-77 (Improper Neutralization of Special Elements used in a Command)

```text
Check this codebase for CVE-2025-50688 and fix it if it is affected.

What it is: CVE-2025-50688 is a medium-severity command injection vulnerability in n/a, published on 5 Aug 2025. 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-2025-50688 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.
