Real-World Exposure
streamlitReal-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
Impact
The initial vulnerability identified in Streamlit apps using custom components, allowing for directory traversal attacks, was addressed in version 1.11.1. However, a minor issue persisted, which could still potentially expose certain files on the server file-system under specific conditions.
Patches
We released an update in version 1.30.0 to further tighten security measures. Users are strongly advised to update to version 1.30.0 immediately for optimal security.
Workarounds
No additional workarounds are necessary once the update to version 1.30.0 is applied.

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 1.30.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8qw9-gf7w-42x5 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-8qw9-gf7w-42x5 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-8qw9-gf7w-42x5. 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-8qw9-gf7w-42x5 in your dependencies?
O3 Security finds GHSA-8qw9-gf7w-42x5 across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
