Due to a logic flaw in the\ndevice’s API authorization mechanism, an attacker can craft requests that\nleverage legitimate “method mapping” behavior to bypass whitelist restrictions,\nallowing restricted operations to be masked as permitted requests and executed.\n\n\n\n\n\nSuccessful\nexploitation may allow an attacker (with access to a restricted account) to\nexecute unauthorized sensitive operations. \nDepending on the operation invoked, impact could include device\nresets, unintended configuration changes, or disruption of normal operation,\nleading to loss of availability and integrity of the device.","cvss_v4":{"vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","score":7.0},"cvss_v3":null,"cwes":["CWE-287"],"references":["https://www.tp-link.com/en/support/download/tapo-c520ws/#Firmware-Release-Notes","https://www.tp-link.com/us/support/download/tapo-c520ws/#Firmware-Release-Notes","https://www.tp-link.com/us/support/faq/5120/"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-34123","score":0.00151,"percentile":0.04272,"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).
