Process crash via improperly propagated native errors
Published Jun 17, 2022 · Updated Sep 17, 2024
Denial of service in Discord.js @discordjs/opus before 0.8.0 allows remote attackers to crash a consuming Node.js process via invalid encoder input. The native OpusEncoder binding throws errors into JavaScript during encoding with zero channels or an uninitialized buffer instead of returning them safely, forcing Node.js to abort. Exploitation requires a consuming application to pass attacker-influenced audio parameters or buffer state into the encoder; the consequence is a hard, unrecoverable process crash.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
