The SEUR Oficial plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'change_service' parameter in all versions up to, and including, 2.2.11 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The SEUR plugin, in its versions prior to 2.5.11, is vulnerable to time-based SQL injection through the use of the ‘id_order’ parameter of the ‘/modules/seur/ajax/saveCodFee.php’ endpoint.

The SEUR Oficial WordPress plugin before 1.7.2 creates a PHP file with a random name when installed, even though it is used for support purposes, it allows to download any file from the web server without restriction after knowing the URL and a password than an administrator can see in the plugin settings page.

The SEUR Oficial WordPress plugin before 1.7.0 does not sanitize and escape some of its settings allowing high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed

yum does not properly handle bad metadata, which allows an attacker to cause a denial of service and possibly have other unspecified impact via a Trojan horse file in the metadata of a remote repository.

The installUpdates function in yum-cron/yum-cron.py in yum 3.4.3 and earlier does not properly check the return value of the sigCheckPkg function, which allows remote attackers to bypass the RMP package signing restriction via an unsigned package.
