Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Name of the Vulnerable Software and Affected Versions Firefox versions prior to 55

Description The issue is related to the lack of same-origin protections for response header name interning, allowing stored header names to be available cross-origin. This could potentially enable a remote attacker to gain unauthorized access to protected information.

Recommendations For versions prior to 55, update to a version 55 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive information until the update can be applied.
