GHSA-5h5v-hw44-f6gg
MEDIUMOceanic allows unsanitized user input to lead to path traversal in URLs
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Blast Radius
oceanic.jsReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects npm packages — download data is not available via public APIs for these ecosystems.
Description
Impact
Input to functions such as Client.rest.channels.removeBan is not url-encoded, resulting in specially crafted input such as ../../../channels/{id} being normalized into the url /api/v10/channels/{id}, and deleting a channel rather than removing a ban.
Workarounds
- Sanitizing user input, ensuring strings are valid for the purpose they are being used for.
- Encoding input with
encodeURIComponentbefore providing it to the library.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for oceanic.js. 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 oceanic.js to 1.10.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5h5v-hw44-f6gg 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-5h5v-hw44-f6gg 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-5h5v-hw44-f6gg. 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-5h5v-hw44-f6gg in your dependencies?
O3 detects GHSA-5h5v-hw44-f6gg across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
