## Affected

- Omnispace Agora Project: fixed in 26.10.0

## Description

Omnispace Agora Project before 26.10.0 contains a broken access control vulnerability in setAffectations() that allows authenticated attackers to insert access-right records for a caller-supplied target space without verifying the caller has rights to that space. Attackers can assign access affectations to spaces outside their own reach, breaking tenant isolation and granting unauthorized access to restricted spaces.
