What is CVE-2025-52136?

In EMQX versions before 5.8.6, a vulnerability exists that allows administrators to install arbitrary plugins via the Dashboard web interface. While the vendor suggests that this behavior is intended, it raises significant security concerns as it can lead to unauthorized plugin installs. Following the release of version 5.8.6, a new defensive feature was introduced, enabling administrators to control plugin acceptability by using the 'emqx ctl plugins allow' command in the CLI. This enhancement adds an extra layer of security to plugin management within the EMQX Dashboard.
