Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. In versions prior to 2.6.0, the SyncViewSet.query_synced_folder() action in cookbook/views/api.py (line 903) fetches a Sync object using get_object_or_404(Sync, pk=pk) without including space=request.space in the filter. This allows an admin user in Space A to trigger sync operations (Dropbox/Nextcloud/Local import) on Sync configurations belonging to Space B, and view the resulting sync logs. Version 2.6.0 patches the issue.
AnalysisAI
Tandoor Recipes versions prior to 2.6.0 allow authenticated admin users to bypass space isolation controls and trigger synchronization operations on Sync configurations belonging to other organizational spaces, exposing the ability to initiate Dropbox, Nextcloud, or local imports outside the attacker's own space and access resulting sync logs. The vulnerability stems from missing space validation in the SyncViewSet.query_synced_folder() API endpoint, enabling horizontal privilege escalation across multi-tenant deployments. …

Vulnerability AssessmentAI
| Risk Assessment | The CVSS 4.0 base score of 5.5 reflects a network-accessible vulnerability requiring high privilege (PR:H - admin role) with no user interaction, but limited scope and no confidentiality or availability impact, only integrity impact (VI:H). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An admin user with credentials in Space A (e.g., Organization A's tenant) could directly query the Sync API endpoint with a primary key belonging to a Sync configuration in Space B. Because the endpoint does not validate space membership, the API would return the sync configuration and permit the attacker to trigger a sync operation, pulling data from Space B's configured external storage (e.g., a shared Dropbox account) and writing it to Space B's database. … |
| Remediation | Upgrade Tandoor Recipes to version 2.6.0 or later immediately. … Detailed patch versions, workarounds, and compensating controls in full report. |
