CVE-2024-42486 Open this link in a new tabHow to fix?
Upgrade github.com/cilium/cilium/operator/pkg/gateway-api to version 1.15.8, 1.16.1 or higher.
Overview
Affected versions of this package are vulnerable to Information Exposure due to incorrect ReferenceGrant update logic in the Gateway API. An attacker can access secrets in other namespaces by exploiting the delay in propagating changes to ReferenceGrants, allowing unauthorized access to sensitive information.
Note: This is only exploitable if the associated ReferenceGrant has been revoked, but the changes have not yet been propagated.
Workaround
This vulnerability can be mitigated by modifying any related Gateway/HTTPRoute/GRPCRoute/TCPRoute CRD, such as adding any label to these resources, which will trigger a reconciliation of ReferenceGrants on an affected cluster.
