Weakness: CWE-284

Description

Directus is a real-time API and App dashboard for managing SQL database content. Directus >=9.23.0, <=v10.5.3 improperly handles _in, _nin operators. It evaluates empty arrays as valid so expressions like {"role": {"_in": $CURRENT_USER.some_field}} would evaluate to true allowing the request to pass. This results in Broken Access Control because the rule fails to do what it was intended to do: Pass rule if **field** matches any of the **values**. This vulnerability is fixed in 10.6.0.

Affected products

directus: from 9.23.0 before 10.6.0 — fixed in 10.6.0

How to fix

Upgrade to a fixed version: directus 10.6.0. Check the vendor advisory for mitigations.
