Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.wildfly.openssl:wildfly-openssl-natives-parent, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.wildfly.openssl:wildfly-openssl-natives-parent to 1.1.3.Final or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2020-25644 is resolved across your whole dependency graph.
Workarounds
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
There is currently no known mitigation for this issue.Source: Red Hat security advisory for CVE-2020-25644 (CC BY 4.0)
