geoskill-mangrove-mapping

Security checks across malware telemetry and agentic risk

Overview

The main mangrove-mapping tool appears local, but the package also includes under-disclosed credential, geocoding, download, and cache code that does not fit the documented offline purpose.

Review this package carefully before installing. The advertised entrypoint appears to do local raster processing, but the shipped package also contains unused or under-disclosed code for third-party geocoding, generic downloads, shared credential-store access, and a hardcoded Earthdata credential. Prefer a version with those helpers removed or clearly gated and with the embedded credential rotated.

MCP Tool Poisoning
Confidence
96% confidence
Finding
If the skill truly performs geocoding, external downloads, credential handling, and contains embedded fallback Earthdata credentials, that is a major mismatch with the documented offline mangrove-mapping purpose and privacy claims. Hidden network access and hardcoded credentials can lead to unauthorized outbound requests, credential leakage, unexpected data exfiltration, and user deception about how their data is handled.

Description-Behavior Mismatch

Medium
Confidence
92% confidence
Finding
The vendored core metadata declares `skill: landsat-download` while this package is presented as a mangrove-mapping skill, creating a provenance and identity mismatch. This can cause reviewers, tooling, or downstream automation to trust the wrong code lineage, potentially masking inappropriate code reuse or substitution of components from another skill.

Context-Inappropriate Capability

Medium
Confidence
89% confidence
Finding
This credentials module handles secrets for unrelated services such as OpenAI, CMA, and EOG in addition to Earthdata/FIRMS. In a skill scoped to mangrove mapping, broad credential brokerage expands the reachable secret surface and increases the chance that other components can access or enumerate credentials not needed for this task.

Context-Inappropriate Capability

Medium
Confidence
92% confidence
Finding
The code is designed to read from broad user-level secret stores and ~/.netrc for multiple external services. Even without immediate exfiltration in this file, this is dangerous because any downstream skill logic can silently inherit access to sensitive user secrets that are outside the mangrove-mapping scope, violating least privilege.

Missing User Warnings

Medium
Confidence
87% confidence
Finding
The code sends user-supplied place queries to third-party geocoding services (Open-Meteo and optionally Nominatim), which can disclose sensitive location intent or operational context without explicit user awareness. In a geospatial skill, AOI names may encode private sites, customer locations, or sensitive project targets, so silent network transmission creates a real privacy and compliance risk.

Missing User Warnings

Medium
Confidence
90% confidence
Finding
The file cache persists normalized queries and resolved AOI metadata under the user's home directory without notice or retention controls. These entries can reveal searched places, areas of interest, and project history to other local users, backup systems, or forensic inspection, which is meaningful in a geospatial analysis workflow.

Missing User Warnings

High
Confidence
99% confidence
Finding
The module contains hardcoded fallback credentials, including a concrete Earthdata username and password. Hardcoded secrets in source are inherently dangerous because anyone with code access can recover and reuse them, and they may be unintentionally propagated into packages, mirrors, backups, or logs.

Natural-Language Policy Violations

Medium
Confidence
76% confidence
Finding
The Nominatim request hard-codes Accept-Language to zh-CN, causing user queries and returned place metadata to be localized to Chinese without consent or configuration. This can leak locale assumptions, reduce result integrity for non-Chinese users, and create privacy/compliance issues in environments where forced regionalization is unexpected.
