Summary

The Hummingbird Performance WordPress plugin before version 3.21.2 does not restrict a network-wide setting to network administrators. This allows an administrator of any single site on a multisite network to execute arbitrary code across the entire network.

Risk Assessment

An administrator of one site in a multisite network can take control of the entire network, potentially leading to full compromise of all sites and data.

Recommendation

Update the Hummingbird Performance plugin to version 3.21.2 or later and review administrator permissions in the multisite network.
