      <title>CVE-2026-54357 — MISP improper authorization allows organization administrators to modify site administrator user settings</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-54357</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; misp&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;</description>
