Fair. But if the site doesn't list vulnerabilities in older firmware, then someone stumbling upon it that hasn't kept their router up to date won't see their actual vulnerabilities listed.
This list is still useless in that case, as it doesn't list the affected firmware versions as far as I can see.
OP here: There is a misunderstanding. The affected firmware versions are always shown in the description text. Its just that in some cases we are not able to show them at the "header" level due to parsing failures
