CVE ID :CVE-2026-19278
Published : Aug. 10, 2026, 12:13 p.m. | 1 hour, 14 minutes ago
Description :A flaw was found in StackRox/RHACS Central's Auth Machine-to-Machine (M2M) token exchange. When an administrator configures M2M role mappings, the system uses unanchored regular expressions for matching claim values. This allows an attacker with a valid OpenID Connect (OIDC) token, whose claim value is a superstring of a configured pattern, to gain unauthorized access to roles they were not intended to receive. This can lead to privilege escalation within the system.
Severity: 6.8 | MEDIUM
