In versions prior to 4.78.3, 4.77.1, 4.76.2, 4.75.2, and 4.53.3, a vulnerability in Fleet's Windows MDM enrollment flow could allow an attacker to submit forged authentication tokens that are not properly validated. Because JWT signatures were not verified, Fleet could accept attacker-controlled identity claims, enabling enrollment of unauthorized devices under arbitrary Azure AD user identities. Versions 4.78.3, 4.77.1, 4.76.2, 4.75.2, and 4.53.3 fix the issue. If an immediate upgrade is not possible, affected Fleet users should temporarily disable Windows MDM.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2026-23518","url":"https://www.suse.com/security/cve/CVE-2026-23518"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"Advisory link for SUSE-SU-2026:0403-1","url":"https://lists.suse.com/pipermail/sle-security-updates/2026-February/024084.html"}],"title":"SUSE CVE CVE-2026-23518","tracking":{"current_release_date":"2026-03-01T00:24:54Z","generator":{"date":"2026-02-07T00:25:06Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2026-23518","initial_release_date":"2026-02-07T00:25:06Z","revision_history":[{"date":"2026-02-07T00:25:06Z","number":"2","summary":"references added,severity changed from  to not set"},{"date":"2026-02-10T00:25:04Z","number":"3","summary":"references added"},{"date":"2026-03-01T00:24:54Z","number":"4","summary":"severity changed from not set to critical"}],"status":"interim","version":"4"}}}
