Name of the Vulnerable Software and Affected Versions: Firefox versions prior to 58

Description: The issue is related to the reader view in Mozilla Firefox, where cross-origin content is displayed despite CORS headers set to prohibit such loading. This could allow access to restricted content. The vulnerability is associated with a lack of protection for service data, potentially enabling a remote attacker to gain unauthorized access to protected information.

Recommendations: For versions prior to 58, update to version 58 or later to resolve the issue. As a temporary workaround, consider disabling the reader view feature until a patch is available. Restrict access to sensitive information when using the reader view in affected versions.
