Lifecycle Timeline
2DescriptionGitHub Advisory
StudioCMS is a server-side-rendered, Astro native, headless content management system. Prior to 0.4.3, the updateUserNotifications endpoint accepts a user ID from the request payload and uses it to update that user's notification preferences. It checks that the caller is logged in but never verifies that the caller owns the target account (id !== userData.user.id). Any authenticated visitor can modify notification preferences for any user, including disabling admin notifications to suppress detection of malicious activity. This vulnerability is fixed in 0.4.3.
Executive ViewAI
Organizations using StudioCMS should be aware of moderate risk from CVE-2026-32104, a IDOR vulnerability rated CVSS 5.4. Exploitation could compromise the security of affected deployments. Organizations should apply vendor updates when available and monitor for exploitation.
Apply vendor patch. If patching is delayed: restrict network access and enable monitoring.
