CVE-2020-37000Public exploit

Code execution via oversized WAV payload

Published Jan 29, 2026 · Updated Jan 29, 2026

Stack buffer overflow in Free MP3 CD Ripper 2.8 allows context-dependent attackers to execute code through a crafted WAV file. The WAV-file import path copies an oversized payload into a fixed stack buffer, overwriting structured exception-handler control data. Execution requires a user to open or convert the file on Windows, after which injected shellcode runs with the application's privileges.
