CVE-2026-6787 is a use of hard-coded cryptographic key vulnerability in WatchGuard Agent on Windows affecting versions before 1.25.03.0000. The flaw is classified as CWE-321 and is described as allowing inclusion of code in an existing process. Available reporting further indicates this issue is one of two chained agent service vulnerabilities addressed in advisory WGSA-2026-00013. In practical exploitation scenarios, a local authenticated attacker with low privileges can abuse the weakness as part of a privilege-escalation chain against the Windows agent, ultimately targeting execution within a trusted process context.
