  "title": "Authorization bypass in Vearch role permissions",
  "summary": "Vearch 3.5.2 through 3.5.9 can fail to enforce configured read-only or no-access permissions on resources assigned through roles. An authenticated non-root user may modify or delete documents and may be able to increase their role privileges, potentially gaining broader administrative access.",
  "mitigation": "Until a corrected Vearch release is available, restrict Vearch access to trusted accounts and tightly limit or block role-management requests such as PUT /roles at the network or API gateway. Review non-root accounts and role memberships, and monitor for unexpected document changes or role updates.",
