{"id":"CVE-2026-27969","summary":"Vitess users with backup storage access can write to arbitrary file paths on restore","details":"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.","aliases":["GHSA-r492-hjgh-c9gw","GO-2026-4570"],"modified":"2026-04-10T05:37:38.090336Z","published":"2026-02-26T01:52:30.677Z","related":["SUSE-SU-2026:1042-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27969.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-22"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27969.json"},{"type":"ADVISORY","url":"https://github.com/vitessio/vitess/security/advisories/GHSA-r492-hjgh-c9gw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27969"},{"type":"FIX","url":"https://github.com/vitessio/vitess/commit/c565cab615bc962bda061dcd645aa7506c59ca4a"},{"type":"FIX","url":"https://github.com/vitessio/vitess/pull/19470"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/vitessio/vitess","events":[{"introduced":"0"},{"fixed":"5b0d3ad22b7553e7a31dc1e02b8005f192cbe039"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"22.0.4"}]}},{"type":"GIT","repo":"https://github.com/vitessio/vitess","events":[{"introduced":"bee41a670a0e18e7400364712263bab171ee89dc"},{"fixed":"0466df5c81c56c9a3d6cad0d38991cf93b657fa2"}],"database_specific":{"versions":[{"introduced":"23.0.0"},{"fixed":"23.0.3"}]}}],"versions":["v0.22.0","v0.22.0-rc1","v0.22.0-rc2","v0.22.0-rc3","v0.22.1","v0.22.2","v0.22.3","v0.23.0","v0.23.1","v0.23.2","v10.0.0-rc1","v10.0.0-rc1-mysql80","v2.0.0-alpha2","v2.0.0-alpha4","v2.0.0-alpha5","v2.0.0-beta.2","v2.0.0-rc.1","v2.0.0-rc.2","v2.1.0-alpha.1","v2.2","v2.2-alpha","v2.2.0-rc.1","v22.0.0","v22.0.0-rc1","v22.0.0-rc2","v22.0.0-rc3","v22.0.1","v22.0.2","v22.0.3","v23.0.0","v23.0.1","v23.0.2","v3.0","v3.0.0-rc.1","v3.0.0-rc.2","v3.0.0-rc.3","v5.0.0","v5.0.1","v6.0.0-rc.1","v7.0.0-beta","v8.0.0-rc1","v9.0.0-rc1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-27969.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:H/VI:H/VA:L/SC:L/SI:H/SA:H"}]}
