CVE-2025-15702 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It affects Cloud Blocks; no fixed version is listed yet.

## Summary

The Cloud Blocks WordPress plugin is affected by an unauthenticated stored cross-site scripting flaw. Because the plugin stores block asset URLs without any authorization or sanitization, an attacker can plant malicious scripts that run in the browser of an administrator or other privileged user when they open the block editor.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

## Description

The Cloud Blocks WordPress plugin through 1.1.8 does not perform any authorisation or sanitisation when storing block asset URLs, allowing unauthenticated users to store malicious scripts that are executed in the browser of any privileged user, such as an administrator, who opens the block editor.
