A deserialization flaw in jackson-databind was found allowing code execution when given maliocusly crafted input to readValue method of ObjectMapper.

In Apache Log4j 2.x before 2.8.2, when using the TCP socket server or UDP socket server to receive serialized log events from another application, a specially crafted binary payload can be sent that, when deserialized, can execute arbitrary code.

CKEditor is vulnerable to a denial of service, caused by a regular expression denial of service (ReDoS) flaw in the dialog plugin. By sending a specially-crafted regex input, a remote attacker could exploit this vulnerability to cause a significant performance drop and results in a browser tab freeze.

CKEditor is vulnerable to cross-site scripting, caused by improper validation of user-supplied input. A remote authenticated attacker could exploit this vulnerability to inject malicious script into a Web page which would be executed in a victim's Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
