CVE-2024-1554

The fetch() API and navigation incorrectly shared the same cache, as the
cache key did not include the optional headers fetch() may contain. Under
the correct circumstances, an attacker may have been able to poison the
local browser cache by priming it with a fetch() response controlled by
the additional headers. Upon navigation to the same URL, the user would see
the cached response instead of the expected response. This vulnerability
affects Firefox < 123.
