The Insert PHP Code Snippet plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.3.6. This is due to missing or incorrect nonce validation in the /admin/snippets.php file. This makes it possible for unauthenticated attackers to activate/deactivate and delete code snippets via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. CVE-2024-43275 appears to be a duplicate of this issue.
The Newsletter Manager plugin for WordPress is vulnerable to insecure deserialization in versions up to, and including, 1.5.1. This is due to unsanitized input from the 'customFieldsDetails' parameter being passed through a deserialization function. This potentially makes it possible for unauthenticated attackers to inject a serialized PHP object.
