CVE-2026-77930 · EvoScientist 0.1.0 before 0.2.5 Human Approval Bypass via Async Sub-Agents
This page contains facts from public vulnerability sources. Check the original advisory before updating.
EvoScientist 0.1.0 before 0.2.5 contains an approval bypass vulnerability that allows attackers to run host shell commands by delegating them to async sub-agents lacking an interrupt_on gate. Attackers can plant instructions in ingested content such as fetched web pages, so the agent calls start_async_task and runs commands with user privileges and environment secrets.
