AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability affects OpenFGA versions 1.8.5 to 1.11.2 and involves improper policy enforcement during certain Check calls. It requires a specific model setup where a relation is assignable both by a type bound public access and a type bound non-public access, with tuples assigned under these conditions and involving objects with lexicographically larger IDs. This flaw can cause the authorization engine to incorrectly enforce permissions.
How can this vulnerability impact me? :
The vulnerability can lead to improper enforcement of authorization policies, potentially allowing unauthorized access or denial of access to resources. This means that users might gain permissions they should not have or be blocked from actions they are authorized to perform, undermining the security and integrity of the system.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
