Prior to 23.0.5 and 24.0.2, twopczHandler in go/vt/vttablet/tabletserver/twopcz.go writes the Action and dtid form values from the vttablet and vtcombo /twopcz HTTP debug endpoint into a text/html response without HTML escaping. Under the default allow-all ACL policy, a remote unauthenticated attacker can send an operator a crafted request that executes script in the operator's browser after the request is opened. The script runs with the vttablet debug origin and can read same-origin diagnostic endpoints that expose query, transaction, environment, variable, or profiling data available in that deployment. This issue is fixed in versions 23.0.5 and 24.0.2.","state":0,"publishedAt":"2026-10-13T20:17:12.453+00:00","modifiedAt":"2026-10-23T15:14:48.24+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://github.com/vitessio/vitess/commit/3140c1846cd120db34f33b2083139b4ab638aed2","https://github.com/vitessio/vitess/commit/976e1e0d78f9d29d02e5e31b4aa7e180648f08af","https://github.com/vitessio/vitess/commit/c1ed96302e658190168c971afdac730cf70e43f7","https://github.com/vitessio/vitess/pull/20255","https://github.com/vitessio/vitess/pull/20273","https://github.com/vitessio/vitess/pull/20274","https://github.com/vitessio/vitess/releases/tag/v23.0.5","https://github.com/vitessio/vitess/releases/tag/v24.0.2","https://github.com/vitessio/vitess/security/advisories/GHSA-v75v-6fpf-gvw8"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-104252","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-79"],"productCriteria":["cpe:2.3:a:linuxfoundation:vitess:*:*:*:*:*:*:*:*"],"sourceDates":{"published":"2026-10-13T20:17:12.453","lastModified":"2026-10-23T15:14:48.240"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
