Miggo AIRoot Cause AnalysisThe vulnerability, CVE-2026-13086, is described as a stack-based buffer overflow within the 'epm' (Endpoint Protection Manager) service of WatchGuard Fireware OS. This occurs when the service processes specially crafted JSON-RPC requests, leading to arbitrary code execution. However, WatchGuard Fireware OS is a proprietary operating system, and no public source code, commit history, or detailed patch information (beyond version numbers) is available. Without access to the source code or specific patch diffs, it is impossible to identify the exact function names, file paths, or precise function signatures that would be involved in triggering this buffer overflow. The advisory indicates the vulnerability is within the 'epm' service's handling of JSON-RPC requests, implying that functions responsible for parsing, validating, or copying data from these requests are where the overflow would occur. However, without concrete evidence from code, any specific function names would be speculative.
