Network-reachable endpoint requires high-privilege auth; scope changes because arbitrary code executes in the server process, enabling impact beyond the application component to the underlying OS.

Lifecycle Timeline
3DescriptionCVE.org
Affected versions of Flowintel improperly trust configuration keys supplied to the alerts settings update endpoint. While configuration values were normalized to Python literals, the corresponding keys were used directly when constructing and replacing lines in conf/config_module.py.
The vulnerable code used requester-controlled keys in both the regular expression and the generated assignment:
f'{key} = {py_val}'
and appended an assignment if the key was not already present. The modified Python configuration module was subsequently reloaded using importlib.reload(). This creates a code-generation boundary in which specially crafted configuration keys can alter the Python source structure and result in execution of attacker-controlled Python statements.

AnalysisAI
Remote code execution in Flowintel's alerts settings update endpoint (versions >= 3.3.0) allows an authenticated high-privileged attacker to inject arbitrary Python statements into the application's live configuration module. The vulnerable endpoint in app/alerts/alerts.py interpolated attacker-supplied configuration keys directly into Python source written to conf/config_module.py, then triggered importlib.reload() - executing injected code in the server process. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated session with high-privilege access (PR:H per the provided CVSS 4.0 vector) to the Flowintel instance - specifically, authorization to call the alerts settings update endpoint. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 8.6 with PR:H reflects that exploitation is gated behind high-privilege authentication, which materially reduces the realistic attacker population compared to unauthenticated vulnerabilities of similar impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained valid high-privilege Flowintel credentials - through phishing, credential reuse against an exposed login page, or insider access - sends a crafted POST request to the alerts settings update endpoint with a configuration key embedding a newline and arbitrary Python (for example, 'WEBHOOK_ENABLED import subprocess; subprocess.Popen(["bash","-i","-c","..."])). Flowintel writes the tampered content into conf/config_module.py and calls importlib.reload(), executing the injected code in the running server process. … |
| Remediation | The primary remediation is to upgrade to a Flowintel release incorporating commit d36171e22aed99055539260bec75e6355ada7d0c, which introduces the ALLOWED_CONFIG_KEYS allowlist and eliminates the injection path entirely. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all Flowintel instances running versions 3.3.0 or later and review access logs for any modifications to alert settings; confirm which administrators hold privileges to update alert configurations. …
