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-954f-xw44-56r2 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 377,166 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.jenkins-ci.plugins:active-directory☕org.jenkins-ci.plugins:active-directoryReal-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
Jenkins Active Directory Plugin implements two separate modes: Integration with ADSI on Windows, and an OS agnostic LDAP-based mode. Optionally, to reduce lookup time, a cache can be configured to remember user lookups and user authentications.
In Active Directory Plugin prior to 2.20 and 2.16.1, when run in Windows/ADSI mode, the provided password was not used when looking up an applicable cache entry. This allows attackers to log in as any user using any password while a successful authentication of that user is still in the cache.
As a workaround for this issue, the cache can be disabled.
Active Directory Plugin 2.20 and 2.16.1 includes the provided password in cache entry lookup.
Additionally, the Java system property hudson.plugins.active_directory.CacheUtil.noCacheAuth can be set to true to no longer cache user authentications.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:active-directory, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.jenkins-ci.plugins:active-directory to 2.20 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-954f-xw44-56r2 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-954f-xw44-56r2 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-954f-xw44-56r2. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-954f-xw44-56r2 in your dependencies?
O3 Security finds GHSA-954f-xw44-56r2 across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
