"The version of Atlassian Confluence Server running on the remote host is affected by a vulnerability as referenced in
the CONFSERVER-104500 advisory.

  - Axios is a promise-based HTTP client for the browser and Node.js. From 1.16.1 until 1.20.0, the RFC 2397
    regular expression allows slash characters on both sides of the media-type separator. An application
    passes an attacker-controlled malformed data URL containing many slash characters and no comma. the
    JavaScript regular-expression engine explores many separator placements before rejecting the URL.
    Synchronous excessive backtracking can block the Node.js event loop and cause denial of service. The
    affected identifiers are fromDataURI, DATA_URL_PATTERN, data:. This issue is fixed in version 1.20.0.
