CVE-2026-57953

Mythic before 3.4.0.60 contains an authorization bypass vulnerability that allows authenticated spectator-role users to perform unauthorized write operations by accessing the eventing_import_automatic_webhook endpoint registered under spectator-permitted middleware. Attackers with spectator role can exploit this misconfigured access control to create and delete automation workflows, making unauthorized modifications to operation automation configuration and EventGroups.
