GHSA-2858-xg23-26fp OpenClaw: Node camera URL payload host-binding bypass allowed gateway fetch pivots

• npm openclaw: >= 2026.2.13, < 2026.3.2 → fixed in 2026.3.2

Summary OpenClaw accepted `camera.snap` / `camera.clip` node payload `url` fields and downloaded them on the gateway/agent host without binding downloads to the resolved node host. In OpenClaw's documented trust model, paired nodes are in the same operator trust boundary, so this is scoped as medium-severity hardening. A malicious or compromised paired node could still steer gateway-host fetches during camera URL retrieval. Affected Packages / Versions • Package: `openclaw` (npm) • Affected versions: `>= 2026.2.13 = 2026.3.2` (released) Technical Details Vulnerable flows accepted URL payloads and downloaded directly from the provided URL: • `src/cli/nodes-camera.ts` (`writeUrlToFile`) fetched URL payloads without node-host binding. • `src/cli/nodes-cli/register.camera.ts` passed `camera.snap` / `camera.clip` payload URLs into that downloader. • `src/agents/tools/nodes-tool.ts` did the same for `camera_snap` / `camera_clip` tool actions. Impact A malicious/compromised paired node could cause gateway-host URL fetches to off-node destinations reachable from the host network. This could be used for internal network probing/fetch pivots in deployments where paired nodes are not fully trusted. Remediation The fix introduces fail-closed node-host binding and guarded fetch for camera URL payload downloads: • Require resolved node host metadata for URL payload downloads. • Enforce hostname match between payload URL and resolved node host. • Use SSRF-guarded fetch with redirect host/protocol checks. • Apply the same enforcement across CLI and agent tool camera paths.
