CVE-2025-10149: Arbitrary Operations via SCIM Endpoints in Multiple WSO2 Products Enables User Account Takeover
The SCIM endpoint does not sufficiently validate authorization for federated users when performing operations against the local user store. This occurs when a local and a federated user share the same username, allowing a federated user to perform actions intended for a local user, including arbitrary operations.
A malicious actor authenticated as a federated user may perform arbitrary operations on local user accounts via the SCIM 2.0 or SCIM 1.1 endpoints when local and federated users share the same username. This could lead to user account takeover. Deployments that do not support user self-registration are considered medium severity.

Event History
Frequently Asked Questions
Which deployments are exposed to this issue?
Exposure requires a local user and a federated user to share the same username, with SCIM 2.0 or SCIM 1.1 endpoints available for operations against the local user store.
What access does an attacker need to exploit the issue?
The attacker must be authenticated as a federated user whose username matches that of a local user. No user interaction is required.
How does user self-registration affect severity?
Deployments that do not support user self-registration are considered medium severity.
