The miniOrange's Google Authenticator WordPress plugin before 5.5 does not have proper authorisation and CSRF checks when handling the reconfigureMethod, and does not validate the parameters passed to it properly. As a result, unauthenticated users could delete arbitrary options from the blog, making it unusable.
Utilities.php in the miniorange-saml-20-single-sign-on plugin before 4.8.84 for WordPress allows XSS via a crafted SAML XML Response to wp-login.php. This is related to the SAMLResponse and RelayState variables, and the Destination parameter of the samlp:Response XML element.
In the miniOrange SAML SP Single Sign On plugin before 4.8.73 for WordPress, the SAML Login Endpoint is vulnerable to XSS via a specially crafted SAMLResponse XML post.
