Open WebUI Cross-Site Request Forgery (CSRF) Vulnerability
Real-World Exposure
open-webuiReal-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
A vulnerability in open-webui/open-webui versions <= 0.3.8 allows remote code execution by non-admin users via Cross-Site Request Forgery (CSRF). The application uses cookies with the SameSite attribute set to lax for authentication and lacks CSRF tokens. This allows an attacker to craft a malicious HTML that, when accessed by a victim, can modify the Python code of an existing pipeline and execute arbitrary code with the victim's privileges.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for open-webui, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update open-webui to 0.3.33 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-85jc-8h5p-8vw8 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-85jc-8h5p-8vw8 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-85jc-8h5p-8vw8. 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-85jc-8h5p-8vw8 in your dependencies?
O3 Security finds GHSA-85jc-8h5p-8vw8 across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
