Real-World Exposure
org.jenkins-ci.plugins:ec2Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Amazon EC2 Plugin 1.50.1 and earlier does not require POST requests in several HTTP endpoints, resulting in cross-site request forgery (CSRF) vulnerabilities. This allows an attacker to provision instances with an attacker-specified template ID.
Amazon EC2 Plugin 1.50.2 now requires POST requests for the affected HTTP endpoints.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:ec2, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.jenkins-ci.plugins:ec2 to 1.50.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2020-2186 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.
