Captured browser activity and request or response bodies are sent to a fixed Timum-controlled ingestion service. - **Trigger:** Mounting the booking widget on an enabled production booking flow starts the recorder. - **Impact:** Booking-flow data, including sensitive values present in network bodies, can be disclosed to the remote session-replay service. - **Evidence paths:** build/booking-B4GF8fhG.js, build/booking-A2D5Gr4l.js, build/booking.umd.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-20T07:17:39.249Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A dynamically loaded chunk creates an OpenReplay tracker with payload capture enabled and invokes its start method from a React effect. - **Attack narrative:** After the consumer mounts the booking widget, its loader imports the main application chunk. That chunk creates a session-replay tracker pointed at a hard-coded external ingestion endpoint, enables request and response payload capture, and automatically starts it for the production booking flow. This creates unconsented remote collection of booking-session activity and network-body data. - **Rationale:** The package contains an automatic, hard-coded production session recorder that captures network payloads and transmits them to a remote vendor endpoint. Header filtering does not prevent sensitive data in request or response bodies from being collected. - **Files touched:** build/booking-B4GF8fhG.js, build/booking-A2D5Gr4l.js, build/booking.umd.cjs - **Network endpoints:** https://openreplay.timum.io/ingest ### Review decision - **Verdict:** Malicious - **Confidence:** 91.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The published module dynamically loads the tracker-containing chunk when booking is mounted., The chunk configures a fixed Timum OpenReplay ingestion endpoint and enables capture of network request and response payloads., The tracker starts automatically in a React effect unless disabled by configuration or the page is a staging/local development API., The CommonJS entry bundle contains the same fixed recorder configuration. - **Evidence against:** The recorder excludes cookie and authorization headers by default., The automatic start is limited to the booking flow and is disabled for listed non-production API hosts. ## Affected versions and remediation This report applies to @timum/booking@1.30.0. - Avoid installing @timum/booking@1.30.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
