WaveSuite CPB Log Files Insufficient Access Control Bypass

WaveSuite contains an insufficient role-based access control (RBAC) vulnerability in its CPB Log Files feature that allows authenticated users with low privileges to access restricted pages by directly requesting URLs intended for higher-privilege roles. This vulnerability (CVE-2026-40463, CVSS 7.6) represents a classic horizontal and vertical privilege escalation risk where authentication alone does not enforce proper authorization boundaries. Organizations using WaveSuite for log management and audit functions are affected, particularly those with multi-tier user hierarchies where data segregation by role is critical for compliance and security operations.

While this CVE currently maps to zero Casky skills, practitioners using Casky.ai would detect similar access control bypass patterns through reconnaissance and privilege escalation detection frameworks mapped to MITRE ATT&CK. Extended reasoning across Casky's 754 security skills would identify suspicious patterns such as authenticated users accessing resources outside their assigned role scope, URL parameter manipulation attempts, or direct requests to administrative endpoints from standard user accounts. Detection would typically surface under techniques like T1087 (Account Discovery), T1010 (Application Window Discovery), or privilege escalation variants where low-privilege sessions suddenly access high-privilege functionality. Security teams would observe anomalous authorization failures, successful access to restricted URLs, or audit logs showing role mismatches—indicators that warrant immediate RBAC policy review and access control testing across authenticated entry points.
