This high-severity CVE scores 7.6 under NVD CVSS v3. EPSS exploit probability: 1.6%, top 27% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

This affects all versions of package osm-static-maps. 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.
