Description · from the CVE record

OpenSRE through 0.1.2026.10.19 contains an approval gate bypass vulnerability that allows attackers to execute shell_run commands without confirmation because the headless presenter's execution_allowed() always returns True. Attackers can inject instructions into alerts or Slack messages triaged by the agent to run commands on the host and exfiltrate LLM, Slack and cloud credentials.
