    CVE-2026-56860Source published Source updated

    Previously, resolving relative paths containing parent directory ('..') segments performed string conversions and buffer rewrites on each step, resulting in quadratic time complexity and high memory allocation overhead. Now, path resolution operates on a byte buffer using index-based backtracking for '..' segments, eliminating the quadratic time complexity and significantly reducing memory allocations. A flaw was found in `net/url`, a component of `golang`. A remote attacker could exploit this by providing a specially crafted path, leading to quadratic time complexity and excessive memory allocation. This can result in a Denial of Service (DoS) due to resource exhaustion. This is an Important denial of service flaw in the Go `net/url` package. Applications built with Go that process…
