CVE-2012-6708: XSS
First published: Thu Jan 18 2018(Updated: )
Affected versions of `jquery` are vulnerable to cross-site scripting. This occurs because the main `jquery` function uses a regular expression to differentiate between HTML and selectors, but does not properly anchor the regular expression. The result is that `jquery` may interpret HTML as selectors when given certain inputs, allowing for client side code execution. ## Proof of Concept ``` $("#log").html( $("element[attribute='<img src=\"x\" onerror=\"alert(1)\" />']").html() ); ``` ## Recommendation Update to version 1.9.0 or later.
