CVE-2024-1854

Summary

CVE-2024-1854 is a stored Cross-Site Scripting (XSS) vulnerability affecting the Essential Blocks – Page Builder plugin for WordPress. This issue, present in versions up to 4.5.1, allows authenticated attackers with contributor access or higher to inject malicious web scripts via the blockId parameter. These scripts will be executed whenever a user accesses an injected page, posing a significant security risk. The vulnerability stems from insufficient input sanitization and output escaping, enabling attackers to exploit the flaw and potentially gain unintended access or perform actions on behalf of the user. It is crucial for WordPress users to update their plugin to the latest version as soon as possible to mitigate this risk.
