AI risk analysis
- Summary
- The flaw in SunEditor allows event-handler attributes to remain on crafted elements, enabling stored cross-site scripting and potentially leading to data exposure or unauthorized actions.
- Exploitability
- Exploitation is moderately hard as it requires crafting specific HTML elements with event handlers, but preconditions include the application rendering attacker-controlled content.
- Blast radius
- If exploited, this could lead to significant data exposure or unauthorized actions within the application's browser context, impacting user data and application integrity.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to version 2.47.11 or later.

NVD description
SunEditor is a lightweight and powerful WYSIWYG editor in vanilla JavaScript with no dependencies. Prior to 2.47.11, the sanitizer in src/lib/core.js does not consistently reject namespaced or custom HTML elements, allowing event-handler attributes to remain on crafted elements. When an application renders attacker-controlled editor content and a user interacts with the element, the retained handler can execute script in the application's browser origin, enabling stored cross-site scripting, data exposure, or unauthorized browser-context actions. This issue is fixed in version 2.47.11.
