Resource-administrator information disclosure via management interfaces
Published May 13, 2026 · Updated May 13, 2026
Information disclosure in F5 BIG-IP and BIG-IQ allows remote authenticated users with resource administrator privileges to view sensitive data. An undisclosed iControl REST endpoint and an undisclosed tmsh command return sensitive information to that role, but F5 has not identified either locus or the authorization error. Reachability requires network access plus resource administrator credentials; the published impact is limited to reading data, with no integrity or availability effect.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
