In Issue #117 with similar structure the project maintainer explains: “DoS vulnerabilities are generally fine in Sass compilers — they are trivially possible with recursive functions, infinite loops, nested mixins, etc. The description here is wrong. Compile time is not expected to be linear relative to the input, and the @extend algorithm is definitionally exponential.”
