GHSA-v492-6xx2-p57g is a medium-severity (CVSS 4.2) CWE-639 vulnerability in chainlit. O3 Security confirms whether GHSA-v492-6xx2-p57g is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Chainlit contains an authorization bypass vulnerability
Real-World Exposure
chainlitReal-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
Chainlit versions prior to 2.8.5 contain an authorization bypass through user-controlled key vulnerability. If this vulnerability is exploited, threads may be viewed or thread ownership may be obtained by an attacker who can log in to the product.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐍PyPI | chainlit | all versions | 2.8.5 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for chainlit. 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 chainlit to 2.8.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v492-6xx2-p57g 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-v492-6xx2-p57g 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-v492-6xx2-p57g. 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-v492-6xx2-p57g in your dependencies?
O3 detects GHSA-v492-6xx2-p57g across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
