CVE-2026-109444 in OpenSRE
Summary
by MITRE • 10/20/2026
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.

The vulnerability identified in OpenSRE versions up to 0.1.2026.10.19 represents a critical failure in access control logic within the system's headless presenter component. This flaw specifically manifests as an approval gate bypass, where the security mechanism designed to require human confirmation for sensitive operations is effectively neutralized. The root cause lies in the execution_allowed() function associated with the headless presenter, which consistently returns True regardless of the context or user intent. In a properly secured system, this function should evaluate specific conditions such as operator privileges, command sensitivity, and explicit approval states before permitting action. By always returning true, the software fails to enforce any form of mandatory human-in-the-loop verification for shell execution commands, thereby removing a critical layer of defense against automated or malicious exploitation.
From an operational perspective, this vulnerability allows attackers who have gained access to alert triage interfaces or Slack message channels integrated with the OpenSRE agent to inject arbitrary instructions that are executed directly on the host system without any confirmation step. The attacker can manipulate the input stream by crafting specific messages within alerts or chat platforms that trigger shell_run commands through the compromised presenter logic. This capability transforms a standard incident response tool into an unauthorized remote code execution vector. Because the approval gate is bypassed, there is no opportunity for security analysts to review and reject malicious payloads before they are executed on production infrastructure.
The impact of this vulnerability extends beyond simple command execution. Attackers can leverage this access to exfiltrate sensitive credentials stored within the environment, including those associated with Large Language Model integrations, Slack workspaces, and various cloud service providers. The ability to run arbitrary shell commands provides a persistent foothold that facilitates lateral movement and deep system compromise. By extracting these high-value secrets, adversaries gain further access to interconnected systems, potentially leading to widespread data breaches or disruption of critical business operations. This scenario aligns with the MITRE ATT&CK technique for Command and Scripting Interpreter abuse, specifically focusing on how attackers use legitimate administrative tools to execute malicious payloads after bypassing initial security controls.
In terms of classification, this vulnerability corresponds closely to CWE-284, which describes Improper Access Control, as well as CWE-798, involving the use of hardcoded credentials or logic that grants excessive privileges by default. The failure to validate execution permissions constitutes a fundamental design flaw in the application's security architecture. To mitigate this risk, immediate remediation should involve patching OpenSRE to version 0.1.2026.10.20 or later where the approval gate logic has been corrected. Until patches are applied, organizations should restrict network access to the headless presenter interface and enforce strict input validation on all alert and message channels connected to the agent. Additionally, implementing least-privilege principles for service accounts used by the OpenSRE agent can limit the scope of damage if exploitation occurs in environments where patching is delayed.
