Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for fr.opensagres.xdocreport:fr.opensagres.xdocreport.template.freemarker, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update fr.opensagres.xdocreport:fr.opensagres.xdocreport.template.freemarker to 2.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-64087 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.
