From 7f512041585f03f1d0edc4b930715272c8a1a201 Mon Sep 17 00:00:00 2001 From: CleverThis Date: Fri, 8 May 2026 20:05:51 +0000 Subject: [PATCH 1/3] fix(security): fix file_tools.py validate_path startswith bypass #7478 Replace the insecure str(target).startswith(str(root)) path validation check in validate_sandbox_path() with Path.relative_to(), preventing sibling directory prefix-collision attacks where a directory like /tmp/abc123-escape would bypass a sandbox root check for /tmp/abc123. Also adds BDD test scenarios exercising the attack across all skill-level file tools (read, write, edit, delete) and updates CHANGELOG.md and CONTRIBUTORS.md.
