Cyborg vulnerabilities

CVE-2026-40213CVE-2026-40214

Summary

Several security issues were fixed in Cyborg.

Details

It was discovered that Cyborg did not properly enforce project ownership in the Accelerator Request (ARQ) API. An authenticated user could possibly use this issue to delete ARQs bound to other projects' instances, resulting in a cross-tenant denial of service. (CVE-2026-40214) It was discovered that Cyborg used a permissive default policy that authorized any request carrying a valid authentication token, regardless of roles or scope, for multiple API endpoints. An authenticated user could possibly use this issue to perform unauthorized actions, such as reprogramming FPGA bitstreams on arbitrary compute nodes. (CVE-2026-40213)
