Cross-guild rule deletion via unscoped global ID
Published Jun 11, 2026 · Updated Jun 11, 2026
Authorization bypass in Vantern Quest Bot before 1.0.5 allows remote authenticated users to delete another guild's AutoMod rules. The chatInputRun removal path accepts a global database ID, fetches the matching row, and deletes it without confirming that its guildId matches the command guild. Exploitation requires normal membership in the victim guild, Manage Server in another guild, and access to the victim rule ID exposed by autocomplete.
