Overview
CVE-2026-52749 is a known-severity vulnerability. It was published on September 28, 2026.
Technical description
The Kaon AR2140X router improperly issues session cookies in responses to unauthenticated HTTP requests. This vulnerability allows a remote attacker to obtain a valid session identifier without providing credentials, resulting in an authentication bypass. With this access, the attacker can perform unauthorized actions on upgrade-related functionalities. These actions can be abused to force the router to issue GET requests to arbitrarily chosen domains.
This issue was identified in firmware versions up to 4.2.17. Status of newer versions remains unknown.
