GHSA-w88m-2936-rmxr is a low-severity (CVSS 3.3) Information Exposure vulnerability in org.wildfly.core:wildfly-server. A fix is available for org.wildfly.core:wildfly-server — see the affected versions and patch details below.
wildfly-core allows user with access to management interface to access vault expression, retrieve item from vault
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
GHSA-w88m-2936-rmxr 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 377,333 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-server☕org.wildfly.core:wildfly-serverReal-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 in all versions. If a vault expression is in the form of a single attribute that contains multiple expressions, a user who was granted access to the management interface can potentially access a vault expression they should not be able to access and possibly retrieve the item which was stored in the vault. The highest threat from this vulnerability is data confidentiality and integrity.

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-server, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.wildfly.core:wildfly-server to 16.0.1.Final or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-w88m-2936-rmxr 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 GHSA-w88m-2936-rmxr can be triaged on real exposure rather than presence alone.
Tailored to GHSA-w88m-2936-rmxr. 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.
Red Hat CodeReady Studio 12 is not affected by this flaw as it does not ship the vulnerable component of wildfly.
