### Impact

HTML files crafted to look like jpg files are able to be uploaded, allowing for XSS.

This affects:

- front-end forms with asset fields without any mime type validation - asset fields in the control panel - asset browser in the control panel

Additionally, if the XSS is crafted in a specific way, the "copy password reset link" feature may be exploited to gain access to a user's password reset token and gain access to their account. The authorized user is required to execute the XSS in order for the vulnerability to occur.

### Patches

In versions 4.46.0 and 3.4.17, the XSS vulnerability has been patched, and the copy password reset link functionality has been disabled. (Users may still trigger password reset emails.)
