CVE-2026-6787
HighCVSS 7.8Exploitation Probability (EPSS)
Low risk1th percentile - higher than 1% of all known CVEs
Summary
Use of hard-coded cryptographic key vulnerability in WatchGuard Agent on Windows allows inclusion of code in existing process.
Risk Assessment
An attacker could use the known key to impersonate or inject malicious code, potentially leading to privilege escalation and system integrity compromise.
Recommendation
Update WatchGuard Agent to a version that does not use hard-coded keys and monitor process integrity.
