Description

Summary Sandbox file operations use check-then-act, bypassing fd-based TOCTOU defenses Current Maintainer Triage • Status: narrow • Normalized severity: medium • Assessment: Released workspace-only apply_patch remove and mkdir operations were still check-then-act, but the draft overstates scope by bundling broader edit paths; keep it open but narrow it to the actual sandbox-workspace mutation boundary. Affected Packages / Versions • Package: `openclaw` (npm) • Latest published npm version: `2026.3.31` • Vulnerable version range: `= 2026.3.31` • First stable tag containing the fix: `v2026.3.31` Fix Commit(s) • `32a4a47d602e0618f87b3e59f94d8c142767f860` — 2026-03-30T16:49:49+01:00 OpenClaw thanks @AntAISecurityLab for reporting.
