Summary

Omnispace Agora Project before 26.10.0 contains a broken access control flaw (CWE-862) that lets a space administrator assign users into spaces they have no authority over. The spaceAffectList affectation runs without checking the caller's rights to the target space. A low-privileged space administrator can break tenant isolation and change user-space assignments in unauthorized spaces over the network, without user interaction.

Description from the CNA

Omnispace Agora Project before 26.10.0 contains a broken access control vulnerability that allows a space administrator to assign users into spaces outside their authority because the spaceAffectList affectation was performed without verifying the caller's rights to the target space. Attackers can exploit the missing readRight() check in the import flow's join INSERT to break tenant isolation and manipulate user-space assignments across unauthorized spaces.
