No affirmative consent gate protects this collection. - **Trigger:** The npm postinstall lifecycle runs unless tracking is explicitly disabled. - **Impact:** The user's Git name, email, and repository ownership information can leave the machine without explicit authorization. - **Evidence paths:** package.json, install/postinstall.cjs, install/git-context.cjs, install/collector.cjs, install/policy.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-05T03:59:53.973Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The collector reads global and consumer Git configuration, extracts identity fields, and includes them in an HTTPS installation event. - **Attack narrative:** Installing the package activates its postinstall collector. Unless an opt-out flag is set, it reads Git configuration from the user's home and consumer checkout, extracts personal identity and repository ownership, and sends those fields to the vendor's growth endpoint. This collection occurs independently of using the AG-UI adapter. - **Rationale:** Source inspection establishes automatic transmission of personal Git information, beyond ordinary anonymous installation telemetry. A vendor-owned destination and opt-out flags do not establish consent for this data collection. - **Files touched:** .gitconfig, git/config - **Network endpoints:** https://threadplane.ai/api/growth/collect/v1/install ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json automatically invokes install/postinstall.cjs, which calls the collector., install/git-context.cjs reads global Git configuration and extracts the user's name and email; it also discovers consumer repository ownership., install/collector.cjs adds the discovered identity to an installation event and sends it by HTTPS POST to the vendor's growth endpoint., install/policy.cjs provides opt-out flags rather than requiring consent before collecting personal Git information. - **Evidence against:** The destination is a fixed vendor endpoint, and tracking can be disabled through environment flags., File reads are bounded; inspected code does not execute a downloaded response or harvest authentication tokens. ## Affected versions and remediation This report applies to @threadplane/ag-ui@0.2.0. - Avoid installing @threadplane/ag-ui@0.2.0. 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.
