GHSA-jhj6-5mh6-4pvf is a medium-severity (CVSS 5.9) NULL Pointer Dereference vulnerability in ktbs.dev/teler. O3 Security confirms whether GHSA-jhj6-5mh6-4pvf is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Denial-of-Service within Docker container
Real-World Exposure
ktbs.dev/telerReal-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
Impact
If you run teler inside a Docker container and encounter errors.Exit function, it will cause denial-of-service (SIGSEGV) because it doesn't get process ID and process group ID of teler properly to kills.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ktbs.dev/teler. 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 ktbs.dev/teler to 0.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jhj6-5mh6-4pvf 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-jhj6-5mh6-4pvf 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-jhj6-5mh6-4pvf. 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-jhj6-5mh6-4pvf in your dependencies?
O3 detects GHSA-jhj6-5mh6-4pvf across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
