Description
Vditor is a browser-side Markdown editor. Versions prior to 3.8.7 are vulnerable to copy-paste cross-site scripting (XSS). For this particular type of XSS, the victim needs to be fooled into copying a malicious payload into the text editor. Version 3.8.7 contains a patch for this issue.
