random_compat Uses insecure CSPRNG
Real-World Exposure
paragonie/random_compatReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
random_compat versions prior to 2.0 are affected by a security vulnerability related to the insecure usage of Cryptographically Secure Pseudo-Random Number Generators (CSPRNG). The affected versions use openssl_random_pseudo_bytes(), which may result in insufficient entropy and compromise the security of generated random numbers.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for paragonie/random_compat, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update paragonie/random_compat to 2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3fmq-x9q6-wm39 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-3fmq-x9q6-wm39 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-3fmq-x9q6-wm39. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-3fmq-x9q6-wm39 in your dependencies?
O3 Security finds GHSA-3fmq-x9q6-wm39 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
