## Summary Android Canvas WebView pages from untrusted origins could invoke the JavascriptInterface bridge and inject instructions into the app. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected: < 2026.3.22 - Fixed: >= 2026.3.22 - Latest released tag checked: `v2026.3.23-2` (`630f1479c44f78484dfa21bb407cbe6f171dac87`) - Latest published npm version checked: `2026.3.23-2` ## Fix Commit(s) - `8b02ef133275be96d8aac2283100016c8a7f32e5` ## Release Status The fix shipped in `v2026.3.22` and remains present in `v2026.3.23` and `v2026.3.23-2`. ## Code-Level Confirmation - apps/android/app/src/main/java/ai/openclaw/app/ui/CanvasScreen.kt now snapshots page origin and rejects untrusted bridge calls. - apps/android/app/src/main/java/ai/openclaw/app/node/CanvasActionTrust.kt centralizes trusted origin and path validation for the bridge. OpenClaw thanks @cyjhhh for reporting.
