CVE-2025-13475: Cross-Tenant Access via Application Consent Mismanagement in Multiple WSO2 Products Allows Unauthorized Data Exposure
- Severity: high (CVSS 7.3 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.3% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-07-04 · updated 2026-10-06
- Weakness: CWE-288
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.
