Payload: Cross-tenant create in @payloadcms/plugin-multi-tenant

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

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.

### Impact An authenticated user limited to one tenant could create a record in another tenant. This requires the multi-tenant plugin with at least one tenant-enabled collection. Reads and direct edits to an existing target-tenant document were not bypassed. You are affected if: - You are using @payloadcms/plugin-multi-tenant ### Patches Users should upgrade Payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`. ### Workarounds You can add access control with `accessResultOverride` on the multi-tenant collection config to ensure a user has access to the tenant before creating.
