CVE-2026-105864

Reads and direct edits of existing documents in the target tenant are not bypassed.

MEDIUM 5.3EPSS 0.20%

Does this matter?

Lower severity and a low EPSS score (0.20%). Track it; it rarely justifies an emergency change on its own.

Description

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, an authenticated user limited to one tenant can create a record in another tenant when at least one tenant-enabled collection exists. Reads and direct edits of existing documents in the target tenant are not bypassed. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.
