Descriptions

Text nodes not in the HTML namespace are incorrectly literally rendered, causing text which should be escaped to not be. This could lead to an XSS attack.

A flaw was found in the Golang HTML package where it is vulnerable to Cross-site scripting caused by the improper validation of user-supplied input. A remote attacker could exploit this vulnerability using a specially crafted URL to execute a script in a victim's web browser within the security context of the hosting website once the URL is clicked. The flaw allows an attacker to steal the victim's cookie-based authentication credentials.

Red Hat OpenShift Container Platform release 4.14.22 is now available with updates to packages and images that fix several bugs and add enhancements. Issues addressed include cross site scripting, denial of service, and traversal vulnerabilities.
