CVE-2026-18167 (GCVE-0-2026-18167)

Vulnerability from cvelistv5 – Published: 2026-09-03 22:24 – Updated: 2026-09-04 18:25

Title

Stack-based buffer overflow in TP-Link Archer AX55 v4

Summary

A stack-based buffer overflow vulnerability exists in the EasyMesh module of TP-Link Archer AX55 v4. When Mesh mode is enabled, a LAN attacker may submit crafted input that causes the easymesh daemon to crash and may potentially achieve remote code execution on the device. Successful exploitation may cause the EasyMesh daemon to crash and may potentially allow remote code execution when Mesh mode is enabled. This may result in high impact to the confidentiality, integrity, and availability of the affected device.

Severity

7.7 (High)

CVE-2026-18330 (GCVE-0-2026-18330)

Vulnerability from cvelistv5 – Published: 2026-09-03 22:24 – Updated: 2026-10-27 17:39

Title

Hardcoded Shared RSA-1024 Private Key in Web Login in TP-Link RE305 and Archer C7

Summary

A hard-coded cryptographic key vulnerability exists in TP-Link RE305 V3 and Archer C7 V5. The same RSA-1024 private key is stored within firmware configuration files and reused across devices. An attacker who obtains the private key and captures an HTTP Web UI login session may use the key to decrypt the administrator password. Successful exploitation may disclose the administrator password captured from an HTTP login session and compromise session confidentiality.

Severity

6.1 (Medium)
