CVE-2025-30237: Authentication Bypass via Broken Access Control in Web Server in Multiple TP-Link Aginet Devices

• Severity: high (CVSS 8.7 v4.0)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-08-10 · updated 2026-10-09
• Weakness: CWE-862

Description

The affected TP-Link Aginet devices contain a flaw in the web management interface where authentication checks are not consistently enforced on certain endpoints. An attacker can send specially crafted requests to bypass authentication and directly invoke privileged functionality without valid credentials. This issue arises from improper enforcement of access control mechanisms on sensitive operations. Successful exploitation may allow an unauthenticated attacker to execute privileged operations and gain full control of the device.
