CVE-2026-81531: CWE-200 Exposure of Sensitive Information to an Unauthorized Actor in TP-Link System Inc. Omada Software Controller
An information disclosure vulnerability has been identified in Omada Controller. An API endpoint intended for Controller initialization remains accessible after completion and may disclose account-related information to unauthenticated remote users. Successful exploitation may allow an attacker to remote query the affected endpoint that may facilitate user enumeration and subsequent attacks targeting administrative accounts.
AI Analysis
Technical Summary
An information disclosure vulnerability (CWE-200) exists in the Omada Software Controller by TP-Link System Inc. An API endpoint designed for controller initialization remains accessible after initialization completes. This endpoint may disclose sensitive account-related information to unauthenticated remote attackers. Successful exploitation could allow attackers to enumerate users and potentially target administrative accounts. The vulnerability has a CVSS 4.0 score of 6.9 (medium severity). No patch or remediation level has been provided by the vendor, and no affected versions are specified.
Potential Impact
The vulnerability allows unauthenticated remote attackers to access sensitive account-related information via an API endpoint that should no longer be accessible after controller initialization. This exposure can facilitate user enumeration and may aid in subsequent attacks against administrative accounts. There is no indication of privilege escalation or direct system compromise from this vulnerability alone.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict network access to the Omada Software Controller management interfaces to trusted users only to reduce exposure. Monitor vendor communications for updates on patches or mitigations.
