The following vulnerabilities exist: - Authors could alter meta data to delete files that they weren't authorized to. - Authors could create posts of unauthorized post types with specially crafted input. - Contributors could craft meta data in a way that resulted in PHP object injection. - Contributors could edit new comments from higher-privileged users, potentially leading to a cross-site scripting vulnerability. - Specially crafted URL inputs could lead to a cross-site scripting vulnerability in some circumstances. WordPress itself was not affected, but plugins could be in some situations. - The user activation screen could be indexed by search engines in some uncommon configurations, leading to exposure of email addresses, and in some rare cases, default generated passwords. - Authors on Apache-hosted sites could upload specifically crafted files that bypass MIME verification, leading to a cross-site scripting vulnerability.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
