## What is CVE-2025-50848?

CVE-2025-50848 is a medium-severity vulnerability in n/a, published on 31 Jul 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

A file upload vulnerability was discovered in CS Cart 4.18.3, allows attackers to execute arbitrary code. CS Cart 4.18.3 allows unrestricted upload of HTML files, which are rendered directly in the browser when accessed. This allows an attacker to upload a crafted HTML file containing malicious content, such as a fake login form for credential harvesting or scripts for Cross-Site Scripting (XSS) attacks. Since the content is served from a trusted domain, it significantly increases the likelihood of successful phishing or script execution against other users.

Check this codebase for CVE-2025-50848 and fix it if it is affected.

What it is: CVE-2025-50848 is a medium-severity vulnerability in n/a, published on 31 Jul 2025. 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-2025-50848 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.
