Threats tagged 'ghsa-v75v-6fpf-gvw8'

Vitess contains a reflected cross-site scripting (XSS) vulnerability in the twopczHandler of the vttablet component. The vulnerability arises because the Action and dtid form values are reflected into the HTML response without proper HTML escaping. This flaw allows an attacker to craft URLs that execute JavaScript in the operator's browser with same-origin access to sensitive debug endpoints. The issue affects all released versions up to the current latest releases and was fixed only on the main development branch as of June 2026. No official CVE or advisory existed at the time of reporting.
