MEDIUMReflected Cross-Site Scripting (XSS) in zenml
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.

Description
A reflected Cross-Site Scripting (XSS) vulnerability was identified in zenml-io/zenml version 0.57.1. The vulnerability exists due to improper neutralization of input during web page generation, specifically within the survey redirect parameter. This flaw allows an attacker to redirect users to a specified URL after completing a survey, without proper validation of the 'redirect' parameter. Consequently, an attacker can execute arbitrary JavaScript code in the context of the user's browser session. This vulnerability could be exploited to steal cookies, potentially leading to account takeover.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for zenml. 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 zenml to 0.58.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3434-hc3m-8mmm 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-3434-hc3m-8mmm 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-3434-hc3m-8mmm. 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-3434-hc3m-8mmm in your dependencies?
O3 detects GHSA-3434-hc3m-8mmm across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
