CVE-2025-10149 · Severity: high · CVSS 8.2 · Published 2026-10-19

WSO2 Identity Server is an identity and access management platform used to authenticate users and manage access to enterprise applications. A security flaw in its SCIM user provisioning endpoints allows attackers authenticated as federated users to take over local user accounts when usernames overlap, potentially gaining full control over those accounts. This affects organizations using federated authentication without user self-registration protections.

## Technical details

The SCIM 2.0 and SCIM 1.1 endpoints fail to properly validate authorization when federated users perform operations against the local user store, specifically when a local and federated user share the same username. A federated user can exploit this to perform arbitrary operations on local accounts, including account takeover. The vulnerability requires the attacker to be authenticated as a federated user and relies on username collision between federated and local user stores.

## Affected products
