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-vpx4-7rfp-h545 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 379,145 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.

Description
Impact
Any user with edit right can execute arbitrary database select and access data stored in the database.
To reproduce:
- In admin, rights, remove scripting rights for {{XWikiAllGroup}}.
- Create a new user without any special privileges.
- Create a page "Private.WebHome" with {{TOKEN_42}} as content. Go to "page administration" and explicitly set all rights for "Admin" to remove them for all other users.
- Logout and login as the unprivileged user. Ensure that the previously created page cannot be viewed.
- Create a new page "ExploitClass.WebHome" and then open it in the class editor (first, make the user an advanced user).
- Add a field named {{ContentList}} of type {{Database List}}
- Enter in field "Hibernate Query" the following content: {noformat}select doc.content, doc.fullName from XWikiDocument as doc where doc.fullName = 'Private.WebHome'{noformat}
- Save the class.
- Open [http://localhost:8080/xwiki/bin/view/ExploitClass/?xpage=suggest&classname=ExploitClass.WebHome&fieldname=ContentList&firCol=doc.fullName&secCol=-]
Patches
The problem has been patched on XWiki 13.10.11, 14.4.7, and 14.10.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.xwiki.platform:xwiki-platform-web, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.xwiki.platform:xwiki-platform-web to 13.10.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vpx4-7rfp-h545 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-vpx4-7rfp-h545 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-vpx4-7rfp-h545. 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-vpx4-7rfp-h545 in your dependencies?
O3 Security finds GHSA-vpx4-7rfp-h545 across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
