# CVE-2026-44364: misp-modules website - Missing CSRF protection in the website home blueprint

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.2% , percentile 10: FIRST’s model estimates a 0.2% chance of exploitation activity in the next 30 days, higher than 10% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs an account (high (admin)). Exposure depends on who can log in.
- Only applies if your dependency tree includes misp-modules (PyPI) <= 3.0.7, no fixed version listed . Check your lockfile, including transitive dependencies.

## What it is

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.

## Affected packages

- PyPI `misp-modules` <= 3.0.7 → fixed: none listed

## Affected products (CVE record)

- MISP misp-modules: <= 3.0.7

## Severity

- GitHub_M CVSS 4.0: 9.3 `CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:H/VI:H/VA:N/SC:H/SI:H/SA:H`
- GitHub CVSS 4.0: 9.3 `CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:H/VI:H/VA:N/SC:H/SI:H/SA:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.21% probability of exploitation activity in the next 30 days; percentile 10.
