Affected versions of `backbone` are vulnerable to cross-site scripting when users are allowed to supply input to the `Model#Escape` function, and the output is then written to the DOM.

The vulnerability occurs as a result of the regular expression used to encode metacharacters failing to take HTML Entities such as `<` into account.

## Recommendation

Update to version 0.5.0 or later.
