CVE-2026-65959Public exploitNetwork attack vector

Unauthorized SQL disclosure via missing debug ACL

Published Aug 18, 2026 · Updated Aug 18, 2026

Authorization bypass in Vitess 24.0.2 and earlier allows remote attackers to read live VReplication SQL data via /debug/vrlog. In go/vt/vttablet/tabletmanager/vreplication/vrlog.go, addHttpEndpoint() routes requests to vrlogStatsHandler() without calling acl.CheckAccessHTTP(r, acl.DEBUGGING), so the handler streams VrLogStats events and embedded SQL statements even when comparable debug endpoints enforce the configured policy. Exploitation requires network reachability to the vttablet debug HTTP port; the consequence is read-only disclosure of replicated statements and bound values, with no reported write or service-interruption path.
