The vulnerability CVE-2026-6787 in WatchGuard Agent involves the use of a hard-coded cryptographic key, which can undermine the security of cryptographic operations within the software. This weakness can allow an attacker with low privileges and local access to include code into an existing process, potentially leading to elevated impact on confidentiality, integrity, and availability. The issue affects versions prior to 1.25.03.0000 on Windows platforms. The CVSS 4.0 vector indicates local attack vector with low attack complexity and no user interaction required, but privileges are required. The vendor has not yet provided an official fix or remediation details.

The vulnerability enables an attacker with local low privileges to potentially inject code into an existing process due to the use of a hard-coded cryptographic key. This can lead to high impact on confidentiality, integrity, and availability of the affected system. However, exploitation requires local access and some privileges, limiting remote exploitation. No known exploits have been reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, limit local access to trusted users only and monitor for suspicious activity related to the WatchGuard Agent process. Avoid deploying affected versions in sensitive environments where possible.
