Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The download path forwards a Geofabrik authorization cookie to any configured PBF URL, including hosts outside Geofabrik, without restricting the destination. This is concrete credential disclosure when a user runs the download with \`OSM\_AUTH\` set. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-01T10:19:45.350Z - **Finished:** 2026-11-01T10:20:55.391Z - **Download time:** 261 ms - **Static scan time:** 127 ms - **AI review time:** 69651 ms - **Total time:** 70041 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The PBF download flow can disclose a Geofabrik authorization cookie to an arbitrary configured host. - **Trigger:** A caller invokes \`run()\` with its default download step, sets \`OSM\_AUTH\`, and configures a non-internal \`pbf\_url\`. - **Impact:** A third-party PBF host can receive an authorization cookie intended for Geofabrik. - **Evidence paths:** dist/index.cjs, dist/config.schema.json - **Review source:** ai\_review - **Reviewed:** 2026-11-01T10:20:55.391Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The code warns that the URL is not Geofabrik’s internal host but continues authentication; it then sends the resulting cookie in a \`Cookie\` header to the configured URL. - **Attack narrative:** When \`OSM\_AUTH\` is set, a non-internal \`pbf\_url\` only triggers a warning; it does not stop authentication. The code obtains a Geofabrik download authorization value, then passes it as a Cookie header to the configured URL with \`curl -L\`. Since the schema accepts an arbitrary URL, a caller can cause that credential to be disclosed to a third-party host during a normal download run. - **Rationale:** The download path forwards a Geofabrik authorization cookie to any configured PBF URL, including hosts outside Geofabrik, without restricting the destination. This is concrete credential disclosure when a user runs the download with \`OSM\_AUTH\` set. - **Files touched:** dist/index.cjs - **Network endpoints:** osm-internal.download.geofabrik.de, www.openstreetmap.org, the host in configured \`pbf\_url\` ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The config schema accepts any string as \`pbf\_url\`; it only recommends Geofabrik’s internal host., For a non-internal PBF URL, the code warns but continues the authentication flow when \`OSM\_AUTH\` is set., After authentication, the code checks for \`gf\_download\_oauth\` and returns that response as the cookie value alongside the original URL., The downloader passes that cookie value in a \`Cookie\` header to the returned URL using \`curl -L\`., Calling \`run()\` downloads by default unless the caller supplies different steps. - **Evidence against:** The package has no install lifecycle scripts, and the download flow runs through the exported \`run()\` function., The username and password from \`OSM\_AUTH\` are posted to OpenStreetMap’s login endpoint; the cross-host disclosure is the resulting Geofabrik authorization cookie. ## Affected versions and remediation This report applies to @osm-conflation-engine/cli@3.6.0. - Avoid installing @osm-conflation-engine/cli@3.6.0. 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.
