Trix is a what-you-see-is-what-you-get rich text editor for everyday writing. Versions prior to 2.1.15 are vulnerable to XSS attacks when pasting malicious code. An attacker could trick a user to copy and paste malicious code that would execute arbitrary JavaScript code within the context of the user's session, potentially leading to unauthorized actions being performed or sensitive information being disclosed. This issue has been patched in version 2.1.15.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
