AI Security Review
scanned 4d ago · by lpm-firewall-aiThe 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.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
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.
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.
AI 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.

Decision evidence
public snapshotAI called this Malicious at 94.0% confidence as Malware with low false-positive risk.
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.
