{"id":"GHSA-cjv3-m589-v3rx","summary":"OpenClaw has Canvas route hardening for mixed-trust deployments","details":"## Summary\nThis advisory tracks a defense-in-depth hardening for canvas routes. In mixed-trust or network-visible deployments, prior canvas auth/fallback behavior could broaden access beyond intended boundaries.\n\n## Deployment Context\nOpenClaw’s default model is trusted host + loopback-first access. Some operators intentionally expose canvas routes on LAN/tailnet. This update is aimed at those broader deployment patterns.\n\n## What Changed\n- Require explicit token or session-capability authorization for canvas routes.\n- Remove shared-IP fallback paths for canvas access.\n- Tighten bind/fallback behavior to fail closed.\n\n## Impact\nRisk was highest in non-loopback or mixed-trust environments. In strict single-operator trusted-host setups, practical exposure is lower.\n\n## Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Vulnerable: `\u003c= 2026.2.19-2`\n- Patched: `2026.2.21` (next release target)\n\n## Fix Commit(s)\n- `c45f3c5b004c8d63dc0e282e2176f8c9355d24f1`\n- `08a7967936cfc0b2af6b27ec1f9272542648ad6c`\n\nThanks @NucleiAv for reporting.","modified":"2026-03-04T15:14:04.950421Z","published":"2026-03-03T23:17:06Z","database_specific":{"nvd_published_at":null,"cwe_ids":["CWE-1021","CWE-79"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-03-03T23:17:06Z"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-cjv3-m589-v3rx"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/08a7967936cfc0b2af6b27ec1f9272542648ad6c"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/c45f3c5b004c8d63dc0e282e2176f8c9355d24f1"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.2.21"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-cjv3-m589-v3rx/GHSA-cjv3-m589-v3rx.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N"}]}
