linkify-it: linkify-it: Denial of Service via algorithmic complexity vulnerability

A flaw was found in linkify-it, a library for recognizing links with full Unicode support. The LinkifyIt.prototype.match function, the package's primary public API, has an algorithmic complexity of ON² for inputs containing many fuzzy links or emails. This can be exploited by a remote attacker...

GHSA-22P9-WV53-3RQ4 LinkifyIt#match scan loop has quadratic algorithmic complexity

Summary LinkifyIt.prototype.match — the package's primary public API — has ON² algorithmic complexity for inputs containing many fuzzy links or emails. This is not a regex backtrack bug; it's a structural issue in the JS-level scan loop that re-slices the input and re-runs unanchored regex search...
