CVE-2026-31990
|
| Summary | OpenClaw: stageSandboxMedia destination symlink traversal can overwrite files outside sandbox workspace ### 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: `<= 2026.3.1` - Patched versions: `>= 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. ### Fix Commit(s) - `17ede52a4be3034f6ec4b883ac6b81ad0101558a` |
