CVE-2026-18330
A hard-coded cryptographic key vulnerability exists in TP-Link RE305 V3 and Archer C7 V5.
Overview
CVE-2026-18330 is a known-severity vulnerability. It was published on September 3, 2026.
Technical description
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.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.

How can CyberStrike help with CVE-2026-18330?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-18330 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
