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.
How urgent is this, really
GHSA-rxff-vr5r-8cj5 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 376,715 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-rxff-vr5r-8cj5 can be triaged on real exposure rather than presence alone.
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 Security finds GHSA-rxff-vr5r-8cj5 across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
