CVE-2026-105860
Payload is a free and open source headless content management system.
Published Oct 6, 2026 · updated Oct 15, 2026 · payloadcms payload
Payload is a free and open source headless content management system. In @payloadcms/plugin-multi-tenant versions before 3.90.0 and canary versions before 4.0.0-canary.34, the default tenant array field access allows an authenticated user to assign the user's own account to other tenants. Deployments that replace the default behavior with secured tenants arrayFieldAccess.create and tenants arrayFieldAccess.update functions are not affected by this behavior. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.
