MediumCVSS 4.3Exploitation Probability (EPSS)
Low risk29th percentile - higher than 29% of all known CVEs
Summary
The asset dependency graph did not restrict nodes by the viewer's DAG read permissions: a user with read access to at least one DAG could browse the asset graph for any other asset in the deployment and learn the existence and names of DAGs and assets outside their authorized scope. Users are recommended to upgrade to version 3.2.1.
Risk Assessment
Potential disclosure of DAG and asset structure information to users without appropriate permissions. This may facilitate further attacks or violate data separation policies.
Recommendation
Upgrade to version 3.2.1 or later. Review user permissions to minimize access scope.
