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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":null}],"references":["https://github.com/vitessio/vitess/security/advisories/GHSA-v75v-6fpf-gvw8","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/commit/3140c1846cd120db34f33b2083139b4ab638aed2","https://github.com/vitessio/vitess/commit/976e1e0d78f9d29d02e5e31b4aa7e180648f08af","https://github.com/vitessio/vitess/commit/c1ed96302e658190168c971afdac730cf70e43f7","https://github.com/vitessio/vitess/releases/tag/v23.0.5","https://github.com/vitessio/vitess/releases/tag/v24.0.2"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-100525","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 13, 2026, 7:22:58 PM","dateUpdated":"Oct 15, 2026, 3:11:35 PM"},"relatedAdvisories":[{"id":"msrc_CVE-2026-104252","title":"Vitess vttablet /twopcz reflected XSS","vulnerabilityIds":["CVE-2026-104252"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
