Snop

**Name of the Vulnerable Software and Affected Versions** Invision Power Services IPS Community Suite versions 4.0.0 through 4.0.12 **Description** A cross-site scripting issue exists, allowing remote authenticated users to inject arbitrary web script or HTML. This is achieved via the `event location[address]` array parameter to the "calendar/submit/" API endpoint. **Recommendations** For versions 4.0.0 through 4.0.12, update to version 4.0.12.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the "calendar/submit/" endpoint until the update is applied. Avoid using the `event location[address]` parameter in the affected endpoint until the issue is resolved.
