Real-World Exposure
github.com/dinever/golfReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
CSRF tokens are generated using math/rand, which is not a cryptographically secure random number generator, allowing an attacker to predict values and bypass CSRF protections with relatively few requests.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/dinever/golf, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/dinever/golf to 0.3.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2016-15005 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.
