A weakness has been identified in vnotex vnote up to 3.20.1. Impacted is an unknown function of the file /src/data/extra/web/js/markdownit.js of the component YAML Frontmatter. This manipulation of the argument p_metaData causes cross site scripting. The attack may be initiated remotely. The vendor was contacted early about this disclosure but did not respond in any way.
