Description

A cross-site scripting (XSS) vulnerability exists in the lxsmnsyc seroval library's JavaScript-output APIs prior to version 1.0.0 and from 1.5.5 up to but not including 1.6.10. The issue arises when regular expressions containing a less-than character are serialized without proper escaping for embedding in HTML script elements. This can allow an attacker to inject malicious scripts if untrusted input is serialized and embedded in a web page. The vulnerability is fixed in version 1.6.10.
