CVE-2023-4961

Summary

CVE-2023-4961 is a Stored Cross-Site Scripting (XSS) vulnerability affecting the Poptin plugin for WordPress. This issue, present in versions up to 1.3, allows authenticated attackers with contributor-level access or higher to inject malicious scripts into 'poptin-form' shortcodes. The shortcoming lies in the plugin's insufficient input sanitization and output escaping, enabling the attacker to execute arbitrary web scripts whenever a user visits an injected page. This poses a significant security risk, potentially leading to data theft or unauthorized account access.
