Load-balancer node manipulation via mis-scoped access controls
Published Apr 23, 2025 · Updated Jun 29, 2026
Incorrect authorization in mod_proxy_cluster 1.3.17 through 1.3.20.Final allows remote authenticated users to alter load-balancer nodes. Example MCMP virtual hosts place Require ip rules inside Directory, which does not restrict requests to the management URL; Location provides the intended scope. Access to the normally non-public MCMP listener is required, after which accepted requests can add, remove, or update balancing nodes.

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.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
