CVE-2025-10149

Arbitrary Operations via SCIM Endpoints in Multiple WSO2 Products Enables User Account Takeover

State: Published
Severity: 8.2 High
Published: Oct 19, 2026
Updated: Oct 20, 2026
Reserved: Sep 9, 2025

Description

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.
