Description
Yuxi is a large-model-based intelligent knowledge base and knowledge graph agent development platform. Prior to version 0.6.2, the project's authentication mechanism contains a flaw. In affected versions, the system does not sufficiently validate the identity token in the Authorization header — only performing a validity check. This allows an administrator token generated in another deployment instance or local testing environment to be used to access the backend management interfaces of a different affected instance. An attacker who obtains or constructs an acceptable administrator Authorization token may bypass normal login authentication and gain administrator privileges. This vulnerability could allow an attacker to access system configurations, invoke backend management APIs, create administrator accounts, and ultimately take over the system backend. This issue has been fixed in version 0.6.2. Before upgrading, users are advised to implement the following temporary measures: Set the environment variable JWT_SECRET_KEY to a non-default value, and configure a unique, sufficiently strong JWT/authentication key for each deployment instance; and/or avoid exposing backend management interfaces directly to the public network.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. 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 the affected component has shipped for CVE-2026-50561 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-2026-50561 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-2026-50561. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
