- GHSA-547x-748v-vp6p
details: "Versions of the package dash-core-components before 2.13.0; all versions
  of the package dash-core-components; versions of the package dash before 2.15.0;
  all versions of the package dash-html-components; versions of the package dash-html-components
  before 2.0.16 are vulnerable to Cross-site Scripting (XSS) when the href of the
  a tag is controlled by an adversary. An authenticated attacker who stores a view
  that exploits this vulnerability could steal the data that's visible to another
  user who opens that view - not just the data already included on the page, but they
  could also, in theory, make additional requests and access other data accessible
  to this user. In some cases, they could also steal the access tokens of that user,
  which would allow the attacker to act as that user, including viewing other apps
  and resources hosted on the same server.\r\r**Note:**\r\rThis is only exploitable
  in Dash apps that include some mechanism to store user input to be reloaded by a
  different user."
