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."}], "lastModified": "2026-10-23T15:14:48.240", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:linuxfoundation:vitess:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "323FA536-9A32-48CC-AC1D-F2271518B540", "versionEndExcluding": "23.0.5"}, {"criteria": "cpe:2.3:a:linuxfoundation:vitess:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "29DB9DB7-5C82-4CAB-BEDF-64C26B17BCA3", "versionEndExcluding": "24.0.2", "versionStartIncluding": "24.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
