CVE-2026-56860

Go

Description

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.
