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-2023-4061 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 376,715 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
org.wildfly.core:wildfly-controllerReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
A flaw was found in wildfly-core. A management user could use the resolve-expression in the HAL Interface to read possible sensitive information from the Wildfly system. This issue could allow a malicious user to access the system and obtain possible sensitive information from the system.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.wildfly.core:wildfly-controller, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.wildfly.core:wildfly-controller to 22.0.0.Final or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-4061 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-2023-4061 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2023-4061. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
This vulnerability requires a malicious user to previously have access to the system, especially access to the HAL interface via browser and logged with a management user who have access to the resolve-expression method, hence the moderate impact.
