The Grey Owl Lightbox plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'gol_button' shortcode in all versions up to, and including, 1.6.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Grey Opaque theme for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘url’ parameter within the theme's Download-Button shortcode in all versions up to, and including, 2.0.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The GREYD.SUITE WordPress theme does not properly validate uploaded custom font packages, and does not perform any authorization or csrf checks, allowing an unauthenticated attacker to upload arbitrary files including php source files, leading to possible remote code execution (RCE).

The Grey's Anatomy Fan (aka nl.jborsje.android.tvfan.greysanatomy) application 3.7.2 for Android 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.

gm-upload.cgi in Greymatter 1.3.1 allows remote authenticated users with upload privileges to execute arbitrary programs by uploading files to locations within the web root. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

Format string vulnerability in the log function in Net::Server 0.87 and earlier, as used in Postfix Greylisting Policy Server (Postgrey) 1.18 and earlier, and possibly other products, allows remote attackers to cause a denial of service (crash) via format string specifiers that are not properly handled before being sent to syslog, as demonstrated using sender addresses to Postgrey.
