CVE-2023-5537

Summary

CVE-2023-5537 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Delete Usermeta plugin for WordPress. Versions up to and including 1.1.2 are vulnerable to this issue. The root cause is the lack of nonce validation in the delumet_options_page() function, allowing unauthenticated attackers to remove user meta for arbitrary users. This can be exploited by tricking a site administrator into performing a specific action, such as clicking on a malicious link. Successful exploitation could lead to significant data loss and potential security breaches. It is recommended that users upgrade to the latest version of the plugin to mitigate this risk.
