Summary

Versions of @payloadcms/plugin-multi-tenant before 3.90.0 and from 4.0.0-canary.0 before 4.0.0-canary.34 in Payload are affected. Missing authorization (CWE-862) in the default tenant array field access lets an authenticated user assign their own account to other tenants. Deployments that replace the default with secured tenants arrayFieldAccess create and update functions are not affected.

Written with Claude Haiku 5.5 from the sources below · 2026-10-29

Description from the CNA

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.
