CVE-2026-10538Network attack vector

Unintended behavior via unrestricted object deserialization

Published Jul 1, 2026 · Updated Jul 1, 2026

Deserialization in BMC Control-M/Server and Enterprise Manager before 9.0.21 allows remote authenticated users to alter server behavior. The messaging consumer reconstructs user-controlled serialized content without restricting the object types that it can instantiate. High-privilege access and complex attack conditions are required; the disclosed consequence is limited to unspecified unintended server-side behavior.
