GHSA-q6qf-4p5j-r25g OpenClaw's image tool bypasses tools.fs.workspaceOnly on sandbox mount paths and exfiltrates out-of-workspace images

• npm openclaw: < 2026.2.23 → fixed in 2026.2.23

Summary In OpenClaw, the sandboxed `image` tool did not honor `tools.fs.workspaceOnly=true` for mounted paths resolved by the sandbox FS bridge. This allowed reading out-of-workspace mounted images (for example `/agent/*`) and forwarding those bytes to vision model providers. Impact Sandbox boundary bypass with confidentiality impact. In affected versions, `read`/`write`/`edit` respected workspace-only guardrails, but `image` could still load mounted out-of-workspace files and exfiltrate them via model requests. Affected Packages / Versions • Package: `openclaw` (npm) • Affected versions: `= 2026.2.23` (released) • Latest published npm at triage time: `2026.2.22-2` Technical Details `workspaceOnly` was enforced in sandbox file tools and `apply_patch`, but not propagated/enforced for `image` sandbox path resolution. The fix threads `workspaceOnly` into image-tool construction and asserts sandbox-root containment before loading media bytes.
