Description (CNA)
Serialize JavaScript serializes JavaScript values to a superset of JSON that includes regular expressions and functions. From 7.1.1 until 7.1.2, function values serialized by serialize-javascript are not fully protected against script-closing tags in attacker-influenced function source because SCRIPT_CLOSE_REGEXP can consume a second closing tag inside one match. When the serialized function is embedded in a script element, the surviving closing tag terminates the element early and causes the remaining output to be parsed as HTML, enabling cross-site scripting in the page origin. Only function values are affected; ordinary data values and options.isJSON output are unaffected. This issue is fixed in version 7.1.2.
