CSRF requires network delivery (AV:N) but mandates victim interaction (UI:R); no privileges needed by attacker, integrity impact limited to dashboard state, no C or A impact.

Lifecycle Timeline
1DescriptionCVE.org
A vulnerability has been found in flask-dashboard Flask-MonitoringDashboard up to 5.0.2. Affected by this issue is some unknown functionality. Such manipulation leads to cross-site request forgery. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Cross-site request forgery in Flask-MonitoringDashboard up to version 5.0.2 allows a remote unauthenticated attacker to trick an authenticated dashboard user into submitting malicious state-changing requests by luring them to a crafted page. The vulnerability (CWE-352) is limited in scope to the monitoring dashboard itself with a low integrity impact and no confidentiality or availability consequence, reflected in the CVSS 4.0 score of 2.1. Exploit details have been publicly disclosed via VulDB submissions and a GitHub issue report, but no patch has been released and the project maintainer has not yet responded to the responsible disclosure.
Technical ContextAI
Flask-MonitoringDashboard is a Python extension for Flask web applications that provides runtime monitoring, request profiling, and performance dashboards (CWE tag: Python). CSRF vulnerabilities (CWE-352) arise when a web application fails to validate that state-changing HTTP requests originate from the legitimate user session rather than a cross-origin attacker-controlled page. The affected functionality is described as 'unknown' in the disclosure, suggesting the reporter identified CSRF tokens missing from one or more dashboard action endpoints - a classic omission in monitoring add-on libraries where security hardening is often deprioritized relative to the core Flask application. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N) confirms a network-reachable, low-complexity attack requiring passive user interaction, with impact confined to limited integrity changes within the vulnerable system only.
RemediationAI
No vendor-released patch has been identified at time of analysis; the project maintainer has not responded to the disclosure per the reporter's note. As an immediate compensating control, organizations should restrict access to the Flask-MonitoringDashboard interface by placing it behind an authenticated reverse proxy or limiting it to trusted internal network segments only - this reduces the attack surface by ensuring potential CSRF targets are not publicly reachable dashboard sessions. Administrators can also consider temporarily disabling the monitoring dashboard in production if its monitoring data is non-critical, by removing the extension from the Flask application factory. Organizations that require the dashboard should monitor the GitHub repository (https://github.com/flask-dashboard/Flask-MonitoringDashboard/issues/557) for a patched release and upgrade immediately when one becomes available. No exact fix version can be cited as none has been confirmed.
