CVE-2026-27969— Vitess 路径遍历漏洞

Vitess users with backup storage access can write to arbitrary file paths on restore

Vitess is a database clustering system for horizontal scaling of MySQL. Prior to versions 23.0.3 and 22.0.4, anyone with read/write access to the backup storage location (e.g. an S3 bucket) can manipulate backup manifest files so that files in the manifest — which may be files that they have also added to the manifest and backup contents — are written to any accessible location on restore. This is a common path traversal security issue. This can be used to provide that attacker with unintended/unauthorized access to the production deployment environment — allowing them to access information available in that environment as well as run any additional arbitrary commands there. Versions 23.0.3 and 22.0.4 contain a patch. No known workarounds are available.

对路径名的限制不恰当(路径遍历)

Vitess 路径遍历漏洞

Vitess是Vitess开源的一个用于水平扩展 MySQL 的数据库集群系统。 Vitess 23.0.3之前版本和22.0.4之前版本存在路径遍历漏洞，该漏洞源于备份清单文件可被操纵，可能导致路径遍历攻击。
