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-r6f3-55wj-g9p3 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

Description
A content spoofing issue exists in WSO2 Identity Server Apps, specifically in the Authentication Portal, due to improper handling of authentication error messages. When an authentication failure occurs, the portal previously accepted an authFailureMsg value supplied via URL and rendered it in the UI without validating it against the resource bundle. An attacker can craft a link that causes the portal to display attacker-controlled text in the error banner, enabling UI misrepresentation and social-engineering.
The fix validates the message key against the resource bundle and encodes input before rendering. Upgrade to org.wso2.identity.apps:authentication-portal 2.4.4 or later to remediate.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.wso2.identity.apps:authentication-portal, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.wso2.identity.apps:authentication-portal to 2.4.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r6f3-55wj-g9p3 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-r6f3-55wj-g9p3 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-r6f3-55wj-g9p3. 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-r6f3-55wj-g9p3 in your dependencies?
O3 Security finds GHSA-r6f3-55wj-g9p3 across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
