This prevents legitimate users from accessing the camera’s live video stream or management interface until the service restarts.","cvss_v4":{"vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":7.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-121"],"references":["https://www.tp-link.com/en/support/download/tapo-c200/v5/#Firmware-Release-Notes","https://www.tp-link.com/kr/support/download/tapo-c200/#Firmware-Release-Notes","https://www.tp-link.com/us/support/download/tapo-c200/v5/#Firmware-Release-Notes","https://www.tp-link.com/us/support/faq/5113/"],"products":["tp-link:tapo_c200_firmware"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-1871","score":0.00305,"percentile":0.23327,"date":"2026-10-31"},"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).
