CVE-2026-56860 on CTRL-OS 26.05

Aliases: CVE-2026-56860

Packages: go_1_27

Status: In Progress, Resolved

Advisory Information

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.
