Severity:
CVSS 4.0: 5.3 (medium)
CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N
Affected versions:
- Apache APISIX 2.3.0 before 3.7.0
Description:
Exposure of data element to wrong session vulnerability in Apache APISIX.
This issue affects Apache APISIX: from 2.3.0 before 3.7.0.
Under a supported authz-keycloak configuration, a request's authorization scope
could persist into later requests on the same route, leading to unintended
authorization expansion and inconsistent access-control decisions.
Users are recommended to upgrade to version 3.7.0 or higher, which fixes the
issue.
