GHSA-6g88-vr3v-76mf is a critical-severity (CVSS 9.8) Code Injection vulnerability in limnoria. O3 Security confirms whether GHSA-6g88-vr3v-76mf is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Eval injection in Supybot/Limnoria
Real-World Exposure
limnoriaReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
Eval injection in the Math plugin of Limnoria (before 2019.11.09) and Supybot (through 2018-05-09) allows remote unprivileged attackers to disclose information or possibly have unspecified other impact via the calc and icalc IRC commands.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for limnoria. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update limnoria to 2019.11.09 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6g88-vr3v-76mf 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 pinpoints whether GHSA-6g88-vr3v-76mf is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-6g88-vr3v-76mf. 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-6g88-vr3v-76mf in your dependencies?
O3 detects GHSA-6g88-vr3v-76mf across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
