## What is CVE-2020-10567?

CVE-2020-10567 is a critical vulnerability in n/a, published on 14 Mar 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

An issue was discovered in Responsive Filemanager through 9.14.0. In the ajax_calls.php file in the save_img action in the name parameter, there is no validation of what kind of extension is sent. This makes it possible to execute PHP code if a legitimate JPEG image contains this code in the EXIF data, and the .php extension is used in the name parameter. (A potential fast patch is to disable the save_img action in the config file.)

Weakness: CWE-20 (Improper Input Validation)

Check this codebase for CVE-2020-10567 and fix it if it is affected.

What it is: CVE-2020-10567 is a critical vulnerability in n/a, published on 14 Mar 2020. 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-2020-10567 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.
