Summary
Mythic before version 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.
Risk Assessment
The risk involves unauthorized access to sensitive C2 configuration data, such as encryption keys, which could lead to compromise of operations and information leakage.
Recommendation
Immediately update Mythic to version 3.4.0.60 or later, which includes a fix for this vulnerability.
Other vulnerabilities in Mythic
See all- CVE-2026-57953Medium
A vulnerability in Mythic before version 3.4.0.60 allows authenticated spectator-role users to bypass authorization and perform unauthorized write operations. Attackers can exploit the misconfigured eventing_import_automatic_webhook endpoint, registered under spectator-permitted middleware, to create and delete automation workflows.
- CVE-2026-57951Medium
A vulnerability in Mythic before version 3.4.0.60 is caused by a broken Hasura permission filter on the payload_build_step table with an always-satisfied _or condition, bypassing operation-scoped access controls. Authenticated operators and spectators can query payload_build_step to read step_stdout, step_stderr, step_name, and step_description across all operations on the server.
