CVE-2026-65959: CWE-862: Missing Authorization in vitessio vitess
CVE-2026-65959 is a medium severity vulnerability in vitessio vitess, a database clustering system for MySQL. Versions 24.0.2 and earlier have a missing authorization check on the /debug/vrlog HTTP endpoint. This allows remote unauthenticated users who can access the debug HTTP port to bypass security policies and stream sensitive VrLogStats data, including SQL statements and bound application values from various workflows.
AI Analysis
Technical Summary
Vitess versions 24.0.2 and earlier expose a missing authorization vulnerability (CWE-862) in the /debug/vrlog endpoint. Unlike other debug endpoints, this endpoint does not invoke acl.CheckAccessHTTP for access control, enabling remote callers with network access to the debug HTTP port to retrieve VrLogStats data. This data includes literal SQL statements and bound application values from MoveTables, Reshard, Materialize, and vitess-strategy Online DDL workflows, potentially leaking sensitive information.
Potential Impact
An unauthenticated remote attacker with access to the vttablet debug HTTP port can bypass configured security policies and obtain sensitive internal logging data. The leaked information includes SQL statements and bound application values, which could aid in reconnaissance or further attacks. The vulnerability does not allow modification or denial of service but compromises confidentiality.
Mitigation Recommendations
No explicit patch or remediation is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict network access to the vttablet debug HTTP port to trusted users only to prevent unauthorized access.
