CVE-2026-109444
CRITICAL 9.3OpenSRE 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.
Severe if exploited (CVSS 9.3), but no known exploitation and low modeled probability. Patch on a normal cadence.
