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-2025-67737 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 377,238 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.
Real-World Exposure
azuracast/azuracastReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
AzuraCast is a self-hosted, all-in-one web radio management suite. Versions 0.23.1 mistakenly include an API endpoint that is intended for internal use by the SFTP software sftpgo, exposing it to the public-facing HTTP API for AzuraCast installations. A user with specific internal knowledge of a station's operations can craft a custom HTTP request that would affect the contents of a station's database, without revealing any internal information about the station. In order to carry out an attack, a malicious user would need to know a valid SFTP station username and the coordinating internal filesystem structure. This issue is fixed in version 0.23.2.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for azuracast/azuracast, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update azuracast/azuracast to 0.23.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-67737 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-2025-67737 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2025-67737. 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-2025-67737 in your dependencies?
O3 Security finds CVE-2025-67737 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
