CVE-2026-33529 is a low-severity (CVSS 3.3) Path Traversal vulnerability in github.com/tobychui/zoraxy. O3 Security confirms whether CVE-2026-33529 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Zoraxy: Authenticated Path Traversal in Config Import leads to RCE
Real-World Exposure

Description
Zoraxy is a general purpose HTTP reverse proxy and forwarding tool. Prior to version 3.3.2, an authenticated path traversal vulnerability in the configuration import endpoint allows an authenticated user to write arbitrary files outside the config directory, which can lead to RCE by creating a plugin. Version 3.3.2 patches the issue.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/tobychui/zoraxy. 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 github.com/tobychui/zoraxy to 3.3.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-33529 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 CVE-2026-33529 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 CVE-2026-33529. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
