svg-sanitizer from 0.11.0 before 1.1.0 contains an algorithmic complexity denial of service vulnerability in hasInfiniteLoop() and countUse() of the use reference-graph analysis. Attackers can upload a small layered SVG with 15 levels of fanned-out use elements, forcing exponential path enumeration that pins PHP workers for hours.
