Headline
GHSA-m5q3-8wgf-x8xf: Directus vulnerable to extraction of password hashes through export querying
Impact
Users with read access to the password field in directus_users can extract the argon2 password hashes by brute forcing the export functionality combined with a _starts_with filter. This allows the user to enumerate the password hashes.
Patches
The problem has been patched by preventing any hashed/concealed field to be filtered against with the _starts_with or other string operator.
Workarounds
Ensuring that no user has read access to the password field in directus_users is sufficient to prevent this vulnerability.

Directus is a real-time API and App dashboard for managing SQL database content. In versions prior to 9.16.0 users with read access to the `password` field in `directus_users` can extract the argon2 password hashes by brute forcing the export functionality combined with a `_starts_with` filter. This allows the user to enumerate the password hashes. Accounts cannot be taken over unless the hashes can be reversed which is unlikely with current hardware. This problem has been patched by preventing any hashed/concealed field to be filtered against with the `_starts_with` or other string operator in version 9.16.0. Users are advised to upgrade. Users unable to upgrade may mitigate this issue by ensuring that no user has `read` access to the `password` field in `directus_users`.
