rocket.chat

Rocket.Chat server before 3.9.0 is vulnerable to a self cross-site scripting (XSS) vulnerability via the drag & drop functionality in message boxes.

The `specializedRendering` function in Rocket.Chat server before 3.9.2 allows a cross-site scripting (XSS) vulnerability by way of the `value` parameter.

An email address enumeration vulnerability exists in the password reset function of Rocket.Chat through 3.9.1.

Rocket.Chat through 3.4.2 allows XSS where an attacker can send a specially crafted message to a channel or in a direct message to the client which results in remote code execution on the client side.

Rocket.Chat before 2.1.0 allows XSS via a URL on a ![title] line.

A reflected XSS issue was discovered in the registration form in Rocket.Chat before 0.66. When one creates an account, the next step will ask for a username. This field will not save HTML control characters but an error will be displayed that shows the attempted username unescaped via packages/rocketchat-ui-login/client/username/username.js in packages/rocketchat-ui-login/client/username/username.html.

An XSS issue was discovered in packages/rocketchat-mentions/Mentions.js in Rocket.Chat before 0.65. The real name of a username is displayed unescaped when the user is mentioned (using the @ symbol) in a channel or private chat. Consequently, it is possible to exfiltrate the secret token of every user and also admins in the channel.
