The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.

Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0, 2.12.3, and 2.3.1.

Cross-site scripting (XSS) vulnerability in McAfee Email and Web Security (EWS) 5.5 through Patch 6 and 5.6 through Patch 3, and McAfee Email Gateway (MEG) 7.0.0 and 7.0.1, allows remote attackers to inject arbitrary web script or HTML via vectors related to the McAfee Security Appliance Management Console/Dashboard.

McAfee Email and Web Security (EWS) 5.5 through Patch 6 and 5.6 through Patch 3, and McAfee Email Gateway (MEG) 7.0.0 and 7.0.1, allows remote attackers to bypass authentication and obtain an admin session ID via unspecified vectors.
