Will It Vibe?target="_blank" without rel="noopener"
Part of Security, which counts for 30% of the overall score. When this check fires it deducts 4 points from that category, once per scan, no matter how many places it turns up.
What it detects
A link opens in a new tab with target="_blank" but no rel="noopener", letting the destination reach back via window.opener (reverse tabnabbing).
Why it matters
A link with target="_blank" but no rel="noopener" gives the newly opened page access to window.opener, which it can use to redirect your original tab to a phishing page while the user is away (reverse tabnabbing). Modern browsers set noopener by default for target=_blank, so this is low risk on current browsers but still worth fixing for older ones and for clarity.
How to fix it
Add rel="noopener" (or rel="noopener noreferrer" when you also want to strip the referrer) to every link that opens in a new tab. For links to external sites this should be the default. If you open tabs with window.open, pass "noopener" in the features argument.
