rbac bypass

The rbac bypass tag covers vulnerabilities that allow authenticated users to circumvent role-based access controls in enterprise software. Recent discussions focus on CVE-2026-44283 in etcd, where transaction-based requests can bypass RBAC to access unauthorized data, and CVE-2025-54551 in FUJIFILM Synapse Mobility, a web-parameter privilege-escalation flaw that exposes protected medical imaging data. These threads highlight how RBAC bypasses often stem from assumptions about uniform enforcement across API paths or from external control of security parameters. The tag is relevant for IT administrators, security researchers, and developers working with distributed systems or healthcare applications where access control integrity is critical.
