CVE-2026-90895

NVD: Affected versions of MISP’s interactive CLI shell implement access control independently from the normal web application, causing several authorization inconsistencies. NVD: The patch shows that CLI access could differ from the web application in multiple security-sensitive areas: - feed listings did not enforce the same lookup_visible restrictions for non-host-organisation users; - feed detail access did not enforce the same... NVD: Those are important hardening changes, but the main vulnerability is the CLI authorization/data-disclosure mismatch.
