+  "details": "## Summary\nBefore `v2026.3.23`, Canvas and A2UI loopback requests could bypass Canvas bearer-or-capability authentication because `authorizeCanvasRequest(...)` treated `isLocalDirectRequest(...)` as an unconditional allow path.\n\n## Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Affected: `< 2026.3.23`\n- Fixed: `>= 2026.3.23`\n- Latest released tag checked: `v2026.3.23-2` (`630f1479c44f78484dfa21bb407cbe6f171dac87`)\n- Latest published npm version checked: `2026.3.23-2`\n\n## Root Cause\nThe vulnerable logic lived in `src/gateway/server/http-auth.ts`. `authorizeCanvasRequest(...)` returned `{ ok: true }` for local-direct requests before checking bearer authentication or an active node canvas capability, which meant unauthenticated loopback Canvas HTTP and WebSocket requests could succeed.\n\n## Fix Commit(s)\n- `d5dc6b6573ae489bc7e5651090f4767b93537c9e` — `fix(gateway): require auth for canvas routes`\n\n## Release Status\nThe fix commit is contained in released tags `v2026.3.23` and `v2026.3.23-2`. The latest shipped tag and npm release both include the fix.\n\n## Code-Level Confirmation\n- `src/gateway/server/http-auth.ts` no longer contains the local-direct early return in `authorizeCanvasRequest(...)`.\n- `src/gateway/server.canvas-auth.test.ts` adds the regression test `denies canvas HTTP/WS on loopback without bearer or capability by default`.\n\nOpenClaw thanks @smaeljaish771 for reporting.",
