## What is CVE-2026-94401?

CVE-2026-94401 is a high-severity server-side request forgery vulnerability in MISP, published on 21 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

MISP has a file-handling vulnerability that could let certain authenticated users make the server read files or access internal network services.

When importing an XML file, MISP did not properly verify that the uploaded content was actually XML. Because of this, a user with permission to modify data could upload a file containing a local file path or a web address instead.

If a local file path was supplied, MISP could read that file from the server. If a URL was supplied, MISP could make a request to that address, including systems that may only be reachable from inside the organization’s network.

The vulnerability could therefore expose sensitive local files and allow unauthorized requests to internal services.

Exploitation required a valid MISP account with modify permissions, but no additional user interaction was needed.

Version affected: <2.5.47

Weakness: CWE-918 (Server-Side Request Forgery), CWE-73 (External Control of File Name or Path)

Check this codebase for CVE-2026-94401 and fix it if it is affected.

What it is: CVE-2026-94401 is a high-severity server-side request forgery vulnerability in MISP, published on 21 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-94401 in the wild and no public exploit code.

Affected product: MISP. 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.
