Title: jQuery Improper Neutralization of Input During Web Page Generation (Cross-site Scripting) Vulnerability
Overview:

jQuery before 1.9.0 is vulnerable to Cross-site Scripting (XSS) attacks. The jQuery(strInput) function does not differentiate selectors from HTML in a reliable fashion. In vulnerable versions jQuery determined whether the input was HTML by looking for the 39lt39 character anywhere in the string giving attackers more flexibility when attempting to construct a malicious payload. In fixed versions jQuery only deems the input to be HTML if it explicitly starts with the 39lt39 character limiting exploitability only to attackers who can control the beginning of a string which is far less common.
