GHSA-cfvj-7rx7-fc7c OpenClaw: stageSandboxMedia destination symlink traversal can overwrite files outside sandbox workspace

• npm openclaw: < 2026.3.2 → fixed in 2026.3.2

Summary `stageSandboxMedia` allowed destination symlink traversal during media staging, which could overwrite files outside the sandbox workspace root. Impact When sandbox media staging handled inbound files, destination writes under `media/inbound` were not destination-alias-safe. If a symlink existed in that destination path, the write could follow it and overwrite host files outside the intended sandbox workspace boundary. Affected Packages / Versions • Package: `openclaw` (npm) • Latest published version checked: `2026.3.1` • Affected: `= 2026.3.2` (released) Root Cause `stageSandboxMedia` validated source paths but wrote destination files with a direct copy path that did not enforce destination boundary/alias checks. Remediation The fix routes staging writes through root-scoped safe write primitives for both local and SCP-staged attachments, preventing destination symlink traversal escapes.
