Vulnerability from github – Published: 2026-06-12 21:31 – Updated: 2026-06-12 21:31

The patch hardens the ACL logic by excluding site administrator accounts from organization administrator–managed user sets, adding explicit authorization failure when a target user is not administrable, and ensuring user setting and login profile operations fail closed.

Severity

5.1 (Medium)

CVE-2026-54357 (GCVE-0-2026-54357)

Vulnerability from cvelistv5 – Published: 2026-06-12 19:25 – Updated: 2026-06-12 20:05

Title

MISP improper authorization allows organization administrators to modify site administrator user settings

Summary

An improper authorization vulnerability in MISP allowed an authenticated organization administrator to access or modify user settings belonging to site administrator accounts within the same organization. The affected access-control checks scoped administrative actions by organization membership but did not exclude higher-privileged site administrator users. As a result, an organization administrator could potentially view or alter site administrator user settings and related login profile information, crossing the intended privilege boundary between organization administration and site-wide administration. The patch hardens the ACL logic by excluding site administrator accounts from organization administrator–managed user sets, adding explicit authorization failure when a target user is not administrable, and ensuring user setting and login profile operations fail closed.

Severity
