No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

Gophish through 0.12.1 contains an insecure direct object reference vulnerability that allows authenticated users to take over other users' groups, templates, landing pages and sending profiles. Attackers can supply another user's sequential id in POST requests to /api/groups/, /api/templates/, /api/pages/ or /api/smtp/ to overwrite and reassign objects, locking out owners and exposing victims' recipient lists.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
