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.
