In WordPress before 5.2.4, unauthenticated viewing of certain content is possible because the static query property is mishandled.

Several vulnerabilities were discovered in Wordpress, a web blogging tool. They allowed remote attackers to perform various Cross-Side Scripting (XSS) and Cross-Site Request Forgery (CSRF) attacks, create files on the server, disclose private information, create open redirects, poison cache, and bypass authorization access and input sanitation.

Several vulnerabilities in wordpress, a web blogging tool, have been fixed.

CVE-2019-17669

Server Side Request Forgery (SSRF) vulnerability because URL validation does not consider the interpretation of a name as a series of hex characters.

CVE-2019-17670

Server Side Request Forgery (SSRF) vulnerability was reported in wp_validate_redirect(). Normalize the path when validating the location for relative URLs.

CVE-2019-17671

Unauthenticated viewing of certain content (private or draft posts) is possible because the static query property is mishandled.

CVE-2019-17675

Wordpress does not properly consider type confusion during validation of the referer in the admin pages. This vulnerability affects the check_admin_referer() WordPress function.

For Debian 8 'Jessie', these problems have been fixed in version 4.1.28+dfsg-0+deb8u1.

We recommend that you upgrade your wordpress packages.

According to its self-reported version number, the detected WordPress application is affected by multiple vulnerabilities :

 - A cross-site scripting (XSS) vulnerability in Customizer.

 - An unspecified issue which could lead to disclosure of unauthenticated posts.

 - A cross-site scripting (XSS) vulnerability in style tags.

 - An unspecified issue which could lead to poison the cache of JSON GET requests via the Vary: Origin header.

 - A server-side request Forgery (SSRF) vulnerability in the way URLs are validated.

 - An unspecified issue related to referrer validation in the admin.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

According to its self-reported version number, the WordPress application running on the remote web server is affected by multiple vulnerabilities:
  - A cross-site scripting (XSS) vulnerability exists due to improper validation of user-supplied input before     returning it to users. An unauthenticated, remote attacker can exploit this, by convincing a user to click a     specially crafted URL, to execute arbitrary script code in a user's browser session.
  - An information disclosure vulnerability exists in Wordpress. An unauthenticated, remote attacker can exploit this     to disclose potentially sensitive information regarding unauthenticated posts.

  - A server-side request forgery vulnerability exists in Wordpress due to insufficient validation of URLs. An     unauthenticated, remote attacker can exploit this, by submitting specifically crafted URLs, to cause the server to     make requests on their behalf. Successful attacks may allow an attacker to request / update data which was not     intended to be accessed by a user of the application.
    Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
