CVE-2025-27980Public exploitNetwork attack vector

Arbitrary file read via invoice parameter

Published Apr 15, 2025 · Updated Apr 15, 2025

Arbitrary file read in Oldmoon Cashbook 4.0.3 allows remote attackers to read server files through the invoice preview endpoint. The disclosure names the invoice parameter as the input but does not publish how the endpoint resolves it to a filesystem path or which validation fails. The endpoint is reachable without credentials, and a crafted invoice value exposes files readable by the Cashbook service.
