What is CVE-2025-15702?
The Cloud Blocks plugin for WordPress, up to version 1.1.8, contains a significant security flaw that allows unauthenticated users to exploit the plugin's functionality. By failing to implement necessary authorization checks and proper sanitization when storing block asset URLs, malicious users can inject harmful scripts. These scripts will then execute in the browsers of any authorized users, including administrators, who access the block editor. This vulnerability underscores the importance of rigorous security practices in plugin development to safeguard against unauthorized access and potential attacks.
Affected Version(s)
Cloud Blocks 0 <= 1.1.8
Exploit Proof of Concept (PoC)
