How to Fix CVE-2020-7749

To remediate this vulnerability, upgrade all affected Osm static maps dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

osm-static-maps fixed: 3.9.0 
npm install osm-static-maps@3.9.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls osm-static-maps

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2020-7749, inspect your project dependencies using npm:

npm ls osm-static-maps

Analyze the terminal output to locate any version of Osm static maps in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.9.0), your application is affected.

Note: The npm ls osm-static-maps command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Osm static maps, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

This affects all versions of package osm-static-maps under 3.9.0. User input given to the package is passed directly to a template without escaping `({{{ ... }}})`. As such, it is possible for an attacker to inject arbitrary HTML/JS code and depending on the context. It will be outputted as an HTML on the page which gives opportunity for XSS or rendered on the server (puppeteer) which also gives opportunity for SSRF and Local File Read.
