CVE-2009-4924: Cross-site Scripting in python-cjson

December 6, 2021 (updated October 25, 2024)

Python-cjson 1.0.5 does not properly handle a [’/’] argument to cjson.encode, which makes it easier for remote attackers to conduct certain cross-site scripting (XSS) attacks involving Firefox and the end tag of a SCRIPT element.
