Real-World Exposure
misp-modulesReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for misp-modules. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of misp-modules has shipped for CVE-2026-44364 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-44364 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-44364. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-44364 in your dependencies?
O3 detects CVE-2026-44364 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
