Technical Description

Multiple vulnerabilities have been identified in WordPress, which could be exploited by attackers to bypass security restrictions or disclose sensitive information.

The first issue is due to an error in the "wp-admin/user-edit.php" script that does not validate the "userid" parameter, which could be exploited by attackers to gain unauthorized access to the metadata of arbitrary users.

The second flaw is due to input validation errors in various scripts (e.g. "wp-includes/functions.php") that do not validate certain parameters before being unserialised, which could be exploited by attackers to cause a denial of service.

The third vulnerability is due to an input validation error in the "plugins/wp-db-backup.php" script, which could be exploited by malicious people to conduct directory traversal attacks.
