Description
FUXA v1.2.7 allows Remote Code Execution (RCE) via the project import functionality. The application does not properly sanitize or sandbox user-supplied scripts within imported project files. An attacker can upload a malicious project containing system commands, leading to full system compromise.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for fuxa-server. 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.
Remediation status
No patched version of fuxa-server has shipped for CVE-2025-69983 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-2025-69983 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-2025-69983. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
