| Doc Text: |
A flaw was found in Tekton Pipelines. A tenant with permissions to create TaskRun or PipelineRun resources can exploit this vulnerability. By omitting the Git API token parameter and pointing the serverURL to an attacker-controlled endpoint, the system-configured Git API token (such as a GitHub Personal Access Token or GitLab token) can be sent to the attacker. This information disclosure allows for the exfiltration of sensitive API tokens.
