City of Edmonton Open Data

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward City of Edmonton open-data CLI, with one CSV-export safety caveat users should understand.

Install only if you are comfortable with a Bash-invoked helper that contacts data.edmonton.ca and may cache the public dataset catalog locally. Treat CSV output as untrusted remote data; prefer JSON for analysis, or sanitize CSV files before opening them in spreadsheet applications.

Finding: Unsafe CSV Export Permits Spreadsheet Formula Injection
Content: View full analysis
permits.csv ``` CSV quoting alone prevents structural corruption but does not prevent spreadsheet applications from interpreting a quoted cell as a formula. Formula-prefixed cells therefore require separate neutralization when the export is intended for spreadsheet use. ### Attack Path 1. An attacker places a formula-prefixed value in a source represented by an Edmonton open dataset, or dataset content is otherwise compromised. 2. A user exports that dataset using `fetch --csv`. 3. The script writes the attacker-controlled value to the CSV output without formula neutralization. 4. The user opens the exported file in spreadsheet software that evaluates ...[truncated 1080 chars]
