Technical Summary
The vulnerability CVE-2026-92359 affects ag-ui-protocol ag-ui version 0.3.0 in the CORSMiddleware component's create_strands_app function located in integrations/aws-strands/python/src/ag_ui_strands/utils.py. It results in a permissive cross-domain policy that includes untrusted domains, potentially allowing cross-origin requests from unauthorized sources. The vulnerability can be exploited remotely but requires a high complexity attack vector. The vendor has provided a fix in version [email protected], identified by patch 9b143b9668fa52c2054ede9d34a45ac4b4401089.
Potential Impact
The vulnerability allows untrusted domains to bypass cross-origin restrictions, which could lead to unauthorized cross-domain interactions. However, the low CVSS score (2.3) and the high complexity required for exploitation indicate limited impact and difficulty in exploitation. There are no known exploits in the wild.
Mitigation Recommendations
Upgrade the affected component to version [email protected], which contains the official fix for this vulnerability. Since this is a cloud service, the vendor manages remediation server-side, but users should verify that their deployments are updated accordingly.
