The assignRoleToUser and assignRoleToGroup handlers (POST /authz/users/{id}/assign and /authz/groups/{id}/assign) only verify the caller may assign roles, unlike role creation, which limits users to permissions they already hold. A user with only assign_and_revoke_users or assign_and_revoke_groups can assign the built-in admin role or any high-privilege custom role to itself or others, gaining full administrative control of the database.","solution":"Fixed in 1.38.0.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-59093","publishedAt":"2026-07-02T20:17:07.410Z","cveId":"CVE-2026-59093","cweIds":["CWE-266"],"cvssScore":"8.8","cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["Weaviate"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Weaviate RBAC role assignment without permission check on assigned roles","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","attackVector":"network","attackComplexity":"low","privilegesRequired":"low","userInteraction":"none","exploitMaturity":"unknown","epssScore":0.00711,"epssCheckedAt":"2026-10-14T12:12:41.218Z","kevDateAdded":null,"advisoryAliases":["GHSA-667j-56pf-pq9c"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-10-10T03:47:07.958Z","patchAvailable":null,"disclosureDate":"2026-07-02T20:17:07.410Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
