GHSA-22p9-wv53-3rq4: LinkifyIt#match scan loop has quadratic algorithmic complexityCVE-2026-48801 0 The LinkifyIt package's primary API function, match(), exhibits O(N²) algorithmic complexity when processing inputs with many fuzzy links or emails. This inefficiency stems from a structural issue in the scan loop that repeatedly slices the input string and runs unanchored regex searches on progressively shorter substrings. This behavior causes significant CPU consumption, leading to denial-of-service conditions when rendering untrusted Markdown with linkify enabled in services such as markdown-it. The vulnerability affects all versions prior to 5.0.1. Join the discussion | GCVE Database | 06/26/2026, 20:47:58 UTC Added: 06/26/2026, 22:04:26 UTC |
