Umbraco · Umbraco · CVE-2015-8813
**Name of the Vulnerable Software and Affected Versions**
Umbraco versions prior to 7.4.0
**Description**
The issue allows remote attackers to conduct server-side request forgery (SSRF) attacks. This is achieved via the `url` parameter in the `Page Load` function. There is no information provided about the estimated number of potentially affected devices worldwide or details about real-world incidents where this issue was exploited.
**Recommendations**
For versions prior to 7.4.0, update to version 7.4.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the `FeedProxy.aspx.cs` file or disabling the `Page Load` function until a patch is available. Avoid using the `url` parameter in the affected API endpoint until the issue is resolved.
