{"cve":"CVE-2023-29195","nvd":{"published":"2023-05-11T20:15:09.403","modified":"2026-06-17T05:49:35.050","status":"Modified","description":"Vitess is a database clustering system for horizontal scaling of MySQL through generalized sharding. Prior to version 16.0.2, users can either intentionally or inadvertently create a shard containing `/` characters from VTAdmin such that from that point on, anyone who tries to create a new shard from VTAdmin will receive an error. Attempting to view the keyspace(s) will also no longer work. Creating a shard using `vtctldclient` does not have the same problem because the CLI validates the input correctly. Version 16.0.2, corresponding to version 0.16.2 of the `go` module, contains a patch for this issue. Some workarounds are available. Always use `vtctldclient` to create shards, instead of using VTAdmin; disable creating shards from VTAdmin using RBAC; and/or delete the topology record for the offending shard using the client for your topology server.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","score":4.3},"cwes":["CWE-20","CWE-703"],"references":["https://github.com/vitessio/vitess/commit/9dcbd7de3180f47e94f54989fb5c66daea00c920","https://github.com/vitessio/vitess/issues/12842","https://github.com/vitessio/vitess/pull/12843","https://github.com/vitessio/vitess/releases/tag/v16.0.2","https://github.com/vitessio/vitess/security/advisories/GHSA-pqj7-jx24-wj7w"],"products":["linuxfoundation:vitess"],"source":"nvd","synced_at":"2026-10-19T21:38:18.424950729+00:00"},"epss":{"cve":"CVE-2023-29195","score":0.00983,"percentile":0.62317,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-pqj7-jx24-wj7w","url":"https://osv.dev/vulnerability/GHSA-pqj7-jx24-wj7w","summary":"VTAdmin users that can create shards can deny access to other functions","modified":"2026-09-10T03:49:53.749637766Z","packages":[{"ecosystem":"Go","name":"vitess.io/vitess","purl":"pkg:golang/vitess.io/vitess","ranges":["<0.16.2"],"fixed":["0.16.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
