[OPEN] Some Instructure owned/created LTI's are blocked when Content Security Policy is enabled

Canvas

Engineers are currently investigating the issue.

Description

When the Content Security Policy is enabled, some Instructure owned LTI Apps are failing to embed content properly.

Expected Behavior

Content is visible.

Workaround

No workaround exists at this time.

Steps to Reproduce

  1. Enable the YouTube LTI tool (Settings > Apps > Search for Youtube > Add App)

  2. Go to Settings > Feature Options > Enable the Content Security Policy feature option

  3. In Settings, go to the Security tab and enable the Content Security Policy

  4. In any course, go to Pages > add a page with a youtube video > Launch youtube from the text editor > select content and embed it (I search “LTI”) - notice that the video does not show in the text editor

  5. Save the page

Result: Embedded content doesn’t load, the error “content on this page violates the security policy, contact your admin for assistance” appears
