Directus Allows Single Sign-On User Enumeration
GitHub lists this reviewed advisory for directus. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

### Impact When relying on SSO providers in combination with local authentication it can be possible to enumerate existing SSO users in the instance. This is possible because if an email address exists in Directus and belongs to a known SSO provider then it will throw a "helpful" error that the user belongs to another provider. ### Reproduction 1. Create a user using a SSO provider `test@directus.io`. 2. Try to log-in using the regular login form (or the API) 3. When using a valid email address | **APP** | **API** | | --- | --- | | !image | !image | 4. When using an invalid email address | **APP** | **API** | | --- | --- | | !image | !image | 5. Using this differing error it is possible to determine whether a specific email address is present in the Directus instance as an SSO user. ### Workarounds When only using
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. FIRST EPSS
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
