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-2024-46987 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 378,156 CVEs with a current EPSS score, this one falls in the 10–50% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure
camaleon_cmsReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects RubyGems packages — download data is not available via public APIs for these ecosystems.
Description
A path traversal vulnerability accessible via MediaController's download_private_file method allows authenticated users to download any file on the web server Camaleon CMS is running on (depending on the file permissions).
In the download_private_file method:
def download_private_file
cama_uploader.enable_private_mode!
file = cama_uploader.fetch_file("private/#{params[:file]}")
send_file file, disposition: 'inline'
end
The file parameter is passed to the fetch_file method of the CamaleonCmsLocalUploader class (when files are uploaded locally):
def fetch_file(file_name)
raise ActionController::RoutingError, 'File not found' unless file_exists?(file_name)
file_name
end
If the file exists it's passed back to the download_private_file method where the file is sent to the user via send_file.
Proof of concept An authenticated user can download the /etc/passwd file by visiting an URL such as:
https://<camaleon-host>/admin/media/download_private_file?file=../../../../../../etc/passwd Impact This issue may lead to Information Disclosure.
Remediation Normalize file paths constructed from untrusted user input before using them and check that the resulting path is inside the targeted directory. Additionally, do not allow character sequences such as .. in untrusted input that is used to build paths.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for camaleon_cms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update camaleon_cms to 2.8.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-46987 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-2024-46987 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2024-46987. 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-2024-46987 in your dependencies?
O3 Security finds CVE-2024-46987 across RubyGems dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
