Tapo App: Improper Certificate Validation

Published Updated By the CyberSecBulletin desk

CVE-2025-9293 is a high-severity improper certificate validation vulnerability in Tapo App from TP-Link, with a CVSS 3.1 base score of 8.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 3.14.111 as the first without the flaw, so updating Tapo App to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.24% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Tapo App to 3.14.111 or a later version.
  2. Update Kasa App to 3.4.350 or a later version.
  3. Update Omada App to 4.25.25 or a later version.
  4. Read the advisory on omadanetworks.com for workarounds and exact fixed builds.
  5. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

A vulnerability in the certificate validation logic may allow applications to accept untrusted or improperly validated server identities during TLS communication. An attacker in a privileged network position may be able to intercept or modify traffic if they can position themselves within the communication channel. Successful exploitation may compromise confidentiality, integrity, and availability of application data.

The underlying weakness: Improper Certificate Validation

The product does not validate, or incorrectly validates, a certificate.

How developers prevent this class of flaw

  • Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
  • If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
