+
+## Token reuse in invitation URLs leads to access control bypass via the use of a different enrollment flow
+
+### Summary
+
+Token reuse in invitation URLs leads to access control bypass via the use of a different enrollment flow than in the one provided.
+
+### Patches
+
+authentik 2022.11.4, 2022.10.4 and 2022.12.0 fix this issue, for other versions the workaround can be used.
+
+### Impact
+
+Only configurations using both invitations and have multiple enrollment flows with invitation stages that grant different permissions are affected. The default configuration is not vulnerable, and neither are configurations with a single enrollment flow.
+
+### Details
+
+The vulnerability allows an attacker that knows different invitation flows names (e.g. `enrollment-invitation-test` and `enrollment-invitation-admin`) via either different invite links or via brute forcing to signup via a single invitation url for any valid invite link received (it can even be a url for a third flow as long as it's a valid invite) as the token used in the `Invitations` section of the Admin interface does NOT change when a different `enrollment flow` is selected via the interface and it is NOT bound to the selected flow, so it will be valid for any flow when used.
+
+### Workarounds
+
+As a workaround, fixed data can be added to invitations which can be checked in the flow to deny requests. Alternatively, an identifier with high entropy (like a UUID) can be used as flow slug, mitigating the attack vector by exponentially decreasing the possibility of discovering other flows.

+## Unauthorized user creation and potential account takeover
+
+### Impact
+
+With the default flows, unauthenticated users can create new accounts in authentik. If a flow exists that allows for email-verified password recovery, this can be used to overwrite the email address of admin accounts and take over their accounts
+
+### Patches
+

+# CVE-2022-46172
+
+## Existing Authenticated Users can Create Arbitrary Accounts
+
+### Summary
+
+Any authenticated user can create an arbitrary number of accounts through the default flows. This would circumvent any policy in a situation where it is undesirable for users to create new accounts by themselves. This may also have carry over consequences to other applications being how these new basic accounts would exist throughout the SSO infrastructure. By default the newly created accounts cannot be logged into as no password reset exists by default. However password resets are likely to be enabled by most installations.
+
+### Patches
+
+authentik 2022.11.4, 2022.10.4 and 2022.12.0 fix this issue.
+
+### Impact
+
+This vulnerability could make it much easier for name and email collisions to occur, making it harder for user to log in. This also makes it more difficult for admins to properly administer users since more and more confusing users will exist. This paired with password reset flows if enabled would mean a circumvention of on-boarding policies. Say for instance a company wanted to invite a limited number of beta testers, those beta testers would be able to create an arbitrary number of accounts themselves.
+
+### Details
+
+This vulnerability has already been submitted over email, this security advisory serves as formalization towards broader information dissemination. This vulnerability pertains to the user context used in the default-user-settings-flow. /api/v3/flows/instances/default-user-settings-flow/execute/
