Description
1. Impacted Products
Streamilt Open Source versions before 1.37.0.
2. Introduction
Snowflake Streamlit open source addressed a security vulnerability via the static file sharing feature. The vulnerability was patched on Jul 25, 2024, as part of Streamlit open source version 1.37.0. The vulnerability only affects Windows.
3. Path Traversal Vulnerability
3.1 Description
On May 12, 2024, Streamlit was informed via our bug bounty program about a path traversal vulnerability in the open source library. We fixed and merged a patch remediating the vulnerability on Jul 25, 2024. The issue was determined to be in the moderate severity range with a maximum CVSSv3 base score of 5.9
3.2 Scenarios and attack vector(s)
Users of hosted Streamlit app(s) on Windows were vulnerable to a path traversal vulnerability when the static file sharing feature is enabled. An attacker could utilize the vulnerability to leak the password hash of the Windows user running Streamlit.
3.3 Resolution
The vulnerability has been fixed in all Streamlit versions released since Jul 25, 2024. We recommend all users upgrade to Version 1.37.0.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for streamlit. 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 streamlit to 1.37.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rxff-vr5r-8cj5 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-rxff-vr5r-8cj5 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-rxff-vr5r-8cj5. 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-rxff-vr5r-8cj5 in your dependencies?
O3 detects GHSA-rxff-vr5r-8cj5 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
