Description
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.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2026-63174 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
