The Swifty Page Manager plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.0.1. This is due to missing or incorrect nonce validation on several AJAX actions handling page creation and deletion among other things. This makes it possible for unauthenticated attackers to invoke those functions, via forged request granted they can trick a site administrator into performing an action such as clicking on a link.

CVE-2023-0088: swifty-page-manager.php in swifty-page-manager/trunk – WordPress Plugin Repository

Red Hat Security Advisory 2022-9098-01

This Metasploit module exploits a command injection vulnerability in the Linear eMerge E3-Series Access Controller. The Linear eMerge E3 versions 1.00-06 and below are vulnerable to unauthenticated command injection in card_scan_decoder.php via the No and door HTTP GET parameter. Successful exploitation results in command execution as the root user.

gf\_swf\_read\_header(read);
