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.

Description
Impact
A user that doesn't have programming rights can execute arbitrary code when creating a page using the Migration Page template. A possible attack vector is the following:
- Create a page and add the following content:
confluencepro.job.question.advanced.input={{/html}} {{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("hello from groovy!"){{/groovy}}{{/async}}
- Use the object editor to add an object of type
XWiki.TranslationDocumentClasswith scopeUSER. - Access an unexisting page using the
MigrationTemplate
http://localhost:8080/xwiki/bin/edit/Page123?template=ConfluenceMigratorPro.Code.MigrationTemplate
It is expected that {{/html}} {{async async="true" cached="false" context="doc.reference"}}{{groovy}}println("hello from groovy!"){{/groovy}}{{/async}} will be present on the page, however, hello from groovy will be printed.
Patches
The issue will be fixed as part of v1.2. The fix was added with commit 35cef22

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.xwiki.confluencepro:application-confluence-migrator-pro-ui. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update com.xwiki.confluencepro:application-confluence-migrator-pro-ui to 1.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6qvp-39mm-95v8 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 pinpoints whether GHSA-6qvp-39mm-95v8 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-6qvp-39mm-95v8. 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-6qvp-39mm-95v8 in your dependencies?
O3 detects GHSA-6qvp-39mm-95v8 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
