CVE-2024-39701: Directus incorrectly handles `_in` filter

July 8, 2024 (updated November 18, 2024)

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.
