An unauthenticated remote attacker may provide specially crafted input influencing backend command execution logic before authentication completes. Exploitation requires the OpenVPN Server feature to be enabled, VPN service reachable by the attacker and attacker to be able to initiate an OpenVPN connection attempt. \n\n\n\nSuccessful exploitation may allow arbitrary command execution, potentially\nleading to full compromise of the affected device.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L","score":9.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-78"],"references":["https://mattg.systems/posts/cve-2026-19586/","https://www.omadanetworks.com/en/support/download/","https://www.omadanetworks.com/us/support/download/","https://www.tp-link.com/us/support/faq/5256/"],"products":["tp-link:dr3150_firmware","tp-link:dr3220v-4g_firmware","tp-link:dr3650v-4g_firmware","tp-link:dr3650v_firmware","tp-link:er603wp-4g-outdoor_firmware","tp-link:er605_firmware","tp-link:er605w_firmware","tp-link:er701-5g-outdoor_firmware","tp-link:er703wp-4g-outdoor_firmware","tp-link:er706w-4g_firmware","tp-link:er706w_firmware","tp-link:er706wp-4g_firmware","tp-link:er707-m2_firmware","tp-link:er7206_firmware","tp-link:er7212pc_firmware","tp-link:er7406_firmware","tp-link:er7412-m2_firmware","tp-link:er8411_firmware"],"source":"nvd","synced_at":"2026-10-26T10:28:23.151169805+00:00"},"epss":{"cve":"CVE-2026-19586","score":0.05724,"percentile":0.92987,"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).
