# CVE-2025-13475: Cross-Tenant Access via Application Consent Mismanagement in Multiple WSO2 Products Allows Unauthorized Data Exposure

- Severity: CVSS 3.5 (Low), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 5.10.0.382, 3.2.0.457, 3.2.1.76
- Published: 2026-07-04 · Updated: 2026-07-06

## Affected

- WSO2 WSO2 Identity Server: from 5.10.0, fixed in 5.10.0.382
- WSO2 WSO2 API Manager: from 3.2.0, fixed in 3.2.0.457; from 3.2.1, fixed in 3.2.1.76

## Description

In multi-tenanted deployments, the application consent management mechanism fails to correctly isolate consent scopes between tenants. Consent granted by a user for a specific SaaS application within one tenant can be incorrectly applied to SaaS applications with the same name in other tenants, leading to unintended cross-tenant consent sharing. This vulnerability may result in the exposure of user data across tenants, enabling SaaS applications in different tenants to access and modify information without explicit user authorization. This can lead to unauthorized data access and privacy violations. This vulnerability has no impact if the deployment does not support multi-tenancy.

## What to do

- Check your stack: if you ship or depend on WSO2 WSO2 Identity Server, WSO2 WSO2 API Manager, upgrade to a fixed version (5.10.0.382, 3.2.0.457, 3.2.1.76) per the references below.
