The injected script is stored and later executed in the context of an administrator's browser (for example after DHCP release/renew triggers the interface to display the stored hostname). Because the management interface uses weak/basic authentication and does not properly protect or isolate session material, the XSS can be used to exfiltrate the admin session and perform administrative actions.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://damiri.fr/en/cve/CVE-2025-65289"],"products":["mercurycom:mr816_firmware"],"source":"nvd","synced_at":"2026-10-19T22:16:40.427100871+00:00"},"epss":{"cve":"CVE-2025-65289","score":0.00319,"percentile":0.24595,"date":"2026-10-25"},"kev":null,"osv":[],"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).
