Description

In EMQX before 5.8.6, administrators can install arbitrary novel plugins via the Dashboard web interface. NOTE: the Supplier's position is that this is the intended behavior; however, 5.8.6 adds a defense-in-depth feature in which a plugin's acceptability (for later Dashboard installation) is set by the "emqx ctl plugins allow" CLI command.

Affected products

EMQX: before 5.8.6 — fixed in 5.8.6

How to fix

Upgrade to a fixed version: EMQX 5.8.6. Check the vendor advisory for mitigations.
