AI-suggested
Upgrade grpc-node to version 1.13.1 or later, or to version 1.14.1 or later to ensure the path matcher performs exact equality comparisons for method names when case-insensitive matching is enabled. No other mitigation is indicated.
Description
A vulnerability in grpc-node versions prior to 1.13.1 and between 1.14.0 and 1.14.1 causes the RBAC path matcher to perform a prefix comparison instead of an equality comparison when case-insensitive matching is enabled. This can lead to incorrect authorization if one method name prefixes another and they have different access rules. The issue is fixed in versions 1.13.1 and 1.14.1.
