## What is CVE-2026-44364?

CVE-2026-44364 is a critical vulnerability in misp-modules, published on 13 May 2026. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.

### Official description

MISP modules are autonomous modules that can be used to extend MISP for new services. In 3.0.7 and earlier, a Cross-Site Request Forgery vulnerability in the MISP Modules website allowed an attacker to cause an authenticated user to submit unintended requests to the home endpoint. The vulnerability was due to the home blueprint being exempted from CSRF protection. This could allow modification of session query data in the context of the authenticated user. The issue was fixed by enabling CSRF protection for the affected blueprint and hardening query parsing.

Weakness: CWE-352 (Cross-Site Request Forgery)

What it is: CVE-2026-44364 is a critical vulnerability in misp-modules, published on 13 May 2026. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2026-44364 in the wild and no public exploit code.

Affected packages and fixed versions:
- misp-modules (PyPI): affected all versions up to 3.0.7; no fix listed
- misp-modules (PyPI): affected all versions up to 3.0.7; no fix listed
- misp-modules (PyPI): affected all versions up to 3.0.7; no fix listed

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.
