Impact
In WSO2’s multi‑tenant products, the application consent mechanism incorrectly isolates consent scopes between tenants. When a user consents to a SaaS application in one tenant, that consent can be incorrectly applied to SaaS applications with the same name in other tenants, allowing unauthorized access to data across tenants. This results in cross‑violating user privacy. The weakness is defined by CWE‑288: Missing Authentication for Critical Function, indicating that process.
Affected Systems
The affected products are WSO2 API Manager and WSO2 Identity Server. The flaw applies to any multi‑tenant deployment of these products where application consent scopes are not tenant‑isolated; specific release versions are not listed in the information provided.
Risk and Exploitability
The CVSS score of 3.5 indicates a low severity. The EPSS score is less than 1%, implying it is not listed in CISA’s KEV catalog, suggesting no known active exploits. The likely attack involves a malicious actor deploying or registering a SaaS application in a tenant other than the one where the target user granted consent, then leveraging normal user consent flows to access data across tenants.
