CVE-2026-112342 Tandoor Recipes CVE debrief
Tandoor Recipes versions before 2.7.0 are vulnerable to cross-space permission cache poisoning. Authenticated users can exploit this by retaining stale group-based permissions across different spaces, allowing for elevated access and bypassing group revocations or demotions. This vulnerability is caused by an improper cache-key design in cookbook/helper/permission_helper.py, which enables attackers to create their own space to obtain an admin group designation and then switch to a victim space where they hold lesser privileges.

Who should care
Defenders responsible for Tandoor Recipes installations, particularly those with multiple users and spaces, should assess exposure and prioritize remediation. They should review user permissions and group assignments, monitor for suspicious activity, and consider compensating controls for exposed systems while remediation is scheduled and verified.
Why it matters
Defenders should care about this vulnerability because it allows authenticated users to exploit stale cached permissions, potentially leading to elevated access and unauthorized actions.
- Elevation of privileges across multiple permission classes and views
- Bypassing of group revocations or demotions
- Potential for unauthorized access to sensitive data
Technical summary
The vulnerability is caused by an improper cache-key design in cookbook/helper/permission_helper.py, which allows authenticated users to retain stale group-based permissions across different spaces. This enables attackers to create their own space to obtain an admin group designation and then switch to a victim space where they hold lesser privileges, potentially leading to elevated access and unauthorized actions across multiple permission classes and views. The vulnerability affects Tandoor Recipes versions before 2.7.0.
Defensive priority
Defenders should prioritize upgrading to version 2.7.0 or later and review user permissions and group assignments.
Recommended defensive actions
- Upgrade to Tandoor Recipes version 2.7.0 or later
- Review user permissions and group assignments
- Monitor for suspicious activity
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
- Review compensating controls for exposed systems while remediation is scheduled and verified.
- Check relevant monitoring, detection, and logs for exposed assets that need extra review.
- Track exceptions, retest remediated assets, and close the item only after evidence is documented.
