CVE-2020-2193Network attack vector

Stored script execution via unescaped parser identifier

Published Jun 3, 2020 · Updated Aug 4, 2024

Stored cross-site scripting in Jenkins ECharts API Plugin 4.7.0-3 and earlier allows remote authenticated users to run script in a viewer's browser. Chart rendering inserts a user-controlled parser identifier into generated page content without escaping it, so stored markup is interpreted as active script. Job/Configure permission is required to plant the value, and execution occurs when another user views the affected chart, exposing that user's Jenkins session context.
