CVE-2023-32192: Rancher API Server Cross-site Scripting Vulnerability

A vulnerability has been identified in which unauthenticated cross-site scripting (XSS) in the API Server’s public API endpoint can be exploited. This can lead to an attacker exploiting the vulnerability to trigger JavaScript code and execute commands remotely.

The attack vector was identified as a Reflected XSS.

API Server propagates malicious payloads from user input to the UI, which renders the output. For example, a malicious URL gets rendered into a script that is executed on a page.
