Red Hat Advanced Cluster Security 4
Monthly
Privilege escalation in Red Hat Advanced Cluster Security 4 (StackRox Central) allows authenticated OIDC token holders to gain unauthorized role assignments through unanchored regular expression matching in the Machine-to-Machine token exchange subsystem. When administrators configure M2M role mappings, RHACS matches incoming OIDC claim values against configured patterns without regex anchors, meaning an attacker whose claim value is a superstring of a mapped pattern - for example, 'superadmin' matching a pattern intended only for 'admin' - receives elevated roles unintentionally. No public exploit code or active exploitation has been identified at this time; the CVSS AC:H rating reflects a genuine complexity barrier requiring attacker knowledge of the target's role mapping configuration.
Deploy-time policy bypass in Red Hat Advanced Cluster Security for Kubernetes 4 lets a user with Kubernetes Deployment-create permission spoof workload identity by setting the openshift.io/encoded-deployment-config label to "null", forcing ACS to record the workload with empty UID, name and labels and a "default" namespace. This evades ACS deploy-time policy detection and enforcement visibility and corrupts Central's persistence, violation reporting and compliance correlation. No public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Denial of service in claircore's Alpine APK package scanner affects Red Hat Advanced Cluster Security 4 and Red Hat Quay 3, where a low-privileged remote attacker can submit a container image containing malformed APK package-database data to trigger an out-of-bounds read (CWE-125) that panics the Go scanner. If the panic is not recovered, the Clair indexer process crashes, interrupting container vulnerability scanning workflows. No public exploit code exists and this CVE is not listed in the CISA KEV catalog, placing this at moderate priority despite network reachability.
Authenticated denial of service in Red Hat Advanced Cluster Security for Kubernetes (RHACS) 4 allows any user holding a valid API token to exhaust Central's resources. Because Central does not cap the nesting depth of queries served on its authenticated GraphQL API, a single deeply nested query can drive excessive CPU and memory consumption and take down the RHACS management plane. No public exploit identified at time of analysis, and the flaw is not listed in CISA KEV, but the low-privilege network vector makes it trivial for any token holder to trigger.
