CVE-2018-25093

Restricted mention use via unchecked tag expansion

Published Nov 6, 2023 · Updated Aug 5, 2024

Improper access control in Vaerys-Dawn DiscordSailv2 2.10.0 through 2.10.2 allows remote authenticated users to send restricted mentions. The Tag Handler expands user-supplied tag content into Discord mentions without enforcing the caller's mention permissions. Membership and command access in the affected Discord server are required, and exploitation can notify users or roles that the caller cannot normally mention.
