Potential Permissions Policy violation Reports

At URIports, we are always looking for ways to improve visibility into security policies and enforcement for web applications. Today, we are excited to announce that URIports now supports potential-permissions-policy-violation reports, providing deeper insights into how embedded content interacts with your site's security policies.

What is potential-permissions-policy-violation?

A Permissions Policy controls which features (such as camera, microphone, or geolocation) can be accessed by a webpage or its embedded iframes. Previously, URIports supported permissions-policy-violation reports, which are triggered when an attempt is made to use a blocked feature despite policy restrictions.

The new potential-permissions-policy-violation report, however, highlights a conflict before the feature is used. This happens when an iframe requests permission for a feature that is restricted by the main document’s Permissions Policy. Even if the iframe does not actually use the feature, the potential conflict is detected and logged.

When is this report triggered?

Consider this scenario:

1. Your webpage enforces a strict Permissions Policy:

Permissions-Policy: camera=()

This completely blocks the camera feature for all content on the page.

2. You embed an iframe from an external origin, and it contains an allow attribute that tries to enable camera access:

<iframe src="https://third-party.com" allow="camera"></iframe>

3. Even if the iframe never attempts to use the camera, the browser detects the mismatch between the document’s Permissions Policy and the iframe’s allow attribute, triggering a potential-permissions-policy-violation report.

Why does this matter?

By capturing these reports, URIports helps web developers and security teams:

• Identify misconfigurations between document policies and embedded content permissions.
• Prevent unintended permission leaks by detecting conflicts before features are used.
• Improve security monitoring by logging policy conflicts that might otherwise go unnoticed.

How to use this feature

URIports users don’t need to take any extra steps—potential-permissions-policy-violation reports are now processed automatically.
