@asamuzakjp/css-color is vulnerable to Denial of Service (DoS)
53
Medium Risk
This Affects:
@asamuzakjp/css-colorTL;DR
The resolveColorMix function in src/js/color.ts destructures the result of several RegExp.match() calls without checking whether the match succeeded. A color-mix() value nested three or more levels deep, or otherwise malformed color-mix input, leaves one of these match calls returning null, and destructuring null throws an uncaught TypeError that propagates to the caller. The patch checks each match result and returns the invalid color fallback instead of destructuring null.
