lakeFS through 1.83.0, fixed in commit 71a45ee, contains an authentication bypass vulnerability in the /setup_comm_prefs endpoint that allows unauthenticated attackers to overwrite operator metadata including email, name, and company after setup completion. Attackers can POST to this endpoint to modify security update preferences, disable security communications, and trigger falsified telemetry events using the legitimate installation ID.
