Prior to version 3.3.2, the lack of sanitization of URLs protocols in the createLink.openLink function enables the execution of arbitrary JavaScript code within the context of the parent page. This is technically indistinguishable from a real page at the rendering level and allows access to the parent page DOM, storage, session, and cookies. If the attacker can specify customIframeId, they can hijack the source of existing iframes. This issue has been patched in version 3.3.2.","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:H/A:N","score":8.2},"cwes":["CWE-79"],"references":["https://github.com/FrontFin/mesh-web-sdk/blob/cf013b85ab95d64c63cbe46d6cb14695474924e7/packages/link/src/Link.ts#L441","https://github.com/FrontFin/mesh-web-sdk/commit/7f22148516d58e21a8b7670dde927d614c0d15c2","https://github.com/FrontFin/mesh-web-sdk/pull/124","https://github.com/FrontFin/mesh-web-sdk/security/advisories/GHSA-vh3f-qppr-j97f"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:10:08.713834912+00:00"},"epss":{"cve":"CVE-2025-59430","score":0.0043,"percentile":0.37,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-vh3f-qppr-j97f","url":"https://osv.dev/vulnerability/GHSA-vh3f-qppr-j97f","summary":"Mesh Connect JS SDK Vulnerable to Cross Site Scripting via createLink.openLink","modified":"2025-09-22T21:58:19Z","packages":[{"ecosystem":"npm","name":"@meshconnect/web-link-sdk","purl":"pkg:npm/%40meshconnect/web-link-sdk","ranges":["<3.3.2"],"fixed":["3.3.2"]}]}],"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).
