Description
XWiki Confluence Migrator Pro helps admins to import confluence packages into their XWiki instance. A user that doesn't have programming rights can execute arbitrary code due to an unescaped translation when creating a page using the Migration Page template. This vulnerability is fixed in 1.2.0.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |

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 CVE-2025-27603 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 CVE-2025-27603 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 CVE-2025-27603. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
