Short explanation
The vttablet and vtcombo /twopcz HTTP debug endpoint in Vitess writes Action and dtid form values without HTML escaping, resulting in a reflected XSS vulnerability.
An unauthenticated attacker can send a crafted request to an operator, executing scripts in their browser and accessing sensitive diagnostic data.
What should be done?
- Upgrade Vitess to versions 23.0.5 or 24.0.2
- Follow vendor security advisories
- Review and restrict ACL policies

Chain of evidence and sources
Vitess vttablet ve vtcombo /twopcz uç noktası Action ve dtid form değerlerini HTML kaçış karakterleri olmadan yansıtır.
Bu zafiyet 23.0.5 ve 24.0.2 sürümlerinde giderilmiştir.
Show the technical text from the sources
Vitess is a database clustering system for horizontal scaling of MySQL. 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.
