Such an attack would require a user to click on a hot spot to execute and would require an attacker-provided configuration. The most plausible potential attack would be if pannellum.htm was hosted on a domain that shared cookies with the targeted site's user authentication; an &lt;iframe&gt; could then be embedded on the attacker's site using pannellum.htm from the targeted site, which would allow the attacker to potentially access information from the targeted site as the authenticated user (or worse if the targeted site did not have adequate CSRF protections) if the user clicked on a hot spot in the attacker's embedded panorama viewer. This was patched in version 2.5.5.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://github.com/mpetroff/pannellum/commit/cc2f3d99953de59db908e0c6efd1c2c17f7c6914","https://github.com/mpetroff/pannellum/security/advisories/GHSA-m52x-29pq-w3vv","https://github.com/mpetroff/pannellum/commit/cc2f3d99953de59db908e0c6efd1c2c17f7c6914","https://github.com/mpetroff/pannellum/security/advisories/GHSA-m52x-29pq-w3vv"],"products":["pannellum:pannellum"],"source":"nvd","synced_at":"2026-10-19T20:59:25.448946135+00:00"},"epss":{"cve":"CVE-2019-16763","score":0.00697,"percentile":0.53063,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-m52x-29pq-w3vv","url":"https://osv.dev/vulnerability/GHSA-m52x-29pq-w3vv","summary":"Pannellum Cross-Site Scripting due to data not being sanitized for URIs or vbscript","modified":"2026-07-08T06:00:39.393569619Z","packages":[{"ecosystem":"npm","name":"pannellum","purl":"pkg:npm/pannellum","ranges":[">=2.5.0 <2.5.5"],"fixed":["2.5.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
