Mythic < 3.4.0.60 - Unauthorized C2 Profile Configuration Access via Unverified Payload UUID

Published Jun 29, 2026 · Updated Nov 8, 2026 · Assigned by VulnCheck

Description

Mythic before 3.4.0.60 contains an authorization bypass vulnerability in four REST endpoints (c2profile_config_check_webhook, c2profile_redirect_rules_webhook, c2profile_get_ioc_webhook, c2profile_sample_message_webhook) that fail to verify payload ownership. An operator in one operation can invoke these endpoints with a known payload UUID from another operation to access that operation's C2 profile configuration including encryption keys and callback parameters.
