## What is CVE-2020-11106?

CVE-2020-11106 is a medium-severity cross-site scripting vulnerability in n/a, published on 30 Mar 2020. 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

An issue was discovered in Responsive Filemanager through 9.14.0. In the dialog.php page, the session variable $_SESSION['RF']["view_type"] wasn't sanitized if it was already set. This made stored XSS possible if one opens ajax_calls.php and uses the "view" action and places a payload in the type parameter, and then returns to the dialog.php page. This occurs because ajax_calls.php was also able to set the $_SESSION['RF']["view_type"] variable, but there it wasn't sanitized.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

Check this codebase for CVE-2020-11106 and fix it if it is affected.

What it is: CVE-2020-11106 is a medium-severity cross-site scripting vulnerability in n/a, published on 30 Mar 2020. 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-2020-11106 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.
