EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2024-47056 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 378,567 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Summary
This advisory addresses a security vulnerability in Mautic where sensitive .env configuration files may be directly accessible via a web browser. This exposure could lead to the disclosure of sensitive information, including database credentials, API keys, and other critical system configurations.
Sensitive Information Disclosure via .env File Exposure: The .env file, which typically contains environment variables and sensitive application configurations, is directly accessible via a web browser due to missing web server configurations that restrict access to such files. This allows an unauthenticated attacker to view the contents of this file by simply navigating to its URL.
Mitigation
Update Mautic to the latest Mautic version.
By default, Mautic does not use .env files for production data.
For Apache users: Ensure your web server is configured to respect .htaccess files.
For Nginx users: As Nginx does not inherently support .htaccess files, you must manually add a configuration block to your Nginx server configuration to deny access to .env files. Add the following to your Nginx configuration for the Mautic site:
location ~ /\.env {
deny all;
}
After modifying your Nginx configuration, remember to reload or restart your Nginx service for the changes to take effect.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mautic/core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update mautic/core to 4.4.16 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-47056 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2024-47056 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2024-47056. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2024-47056 in your dependencies?
O3 Security finds CVE-2024-47056 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
