The Content Views – Post Grid, Slider, Accordion (Gutenberg Blocks and Shortcode) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 3.6.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

The NTV News24 prior to Ver.3.0.0 does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

Multiple cross-site scripting (XSS) vulnerabilities in index.php in Rentventory 1.0.1 allow remote attackers to inject arbitrary web script or HTML via the (1) username (aka Login) and (2) password parameters in a login action.

SQL injection vulnerability in index.php in Rentventory allows remote attackers to execute arbitrary SQL commands via the product parameter.

Cross-site scripting (XSS) vulnerability in Antville 1.1 allows remote attackers to inject arbitrary web script or HTML via the notfound.skin error document.
