AI Analysis
Technical Summary
This vulnerability (CWE-488) in Apache APISIX occurs when authorization scopes from one request persist improperly into later requests on the same route under an authz-keycloak configuration. This persistence can cause authorization scopes to expand unintentionally, resulting in inconsistent access control decisions. The flaw affects Apache APISIX versions >=2.3.0 and <3.7.0. Upgrading to version 3.7.0 or higher resolves the issue.
Potential Impact
The vulnerability allows authorization scopes to persist across requests incorrectly, potentially granting users broader access than intended. This leads to inconsistent and expanded access control decisions, which could compromise the intended security boundaries within the application.
Mitigation Recommendations
Users should upgrade Apache APISIX to version 3.7.0 or later, where this issue is fixed. No other mitigation steps are indicated.
