Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-30859 exists.\n\nAffected packages and fixed versions:\n- github.com/Tencent/WeKnora (Go): affected all versions; no fix listed\n- github.com/Tencent/WeKnora (Go): affected all versions; fixed in 0.2.12\n- github.com/Tencent/WeKnora (Go): affected all versions; fixed in 0.2.12\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-30859/ (Markdown: https://insights.sbomify.com/CVE-2026-30859/index.md)","id":"CVE-2026-30859","markdown":"https://insights.sbomify.com/CVE-2026-30859/index.md","name":"CVE-2026-30859","record":{"aliases":["GHSA-2f4c-vrjq-rcgv","GO-2026-4637"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"LLM document framework","requires_auth":"low_privilege","summary":"Authenticated users can access other tenants' sensitive data due to missing tenant isolation checks in the database query tool.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"weknora","vendor":"tencent"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"WeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval.

The application fails to enforce tenant isolation on critical tables (models, messages, embeddings), enabling unauthorized cross-tenant data access with user-level authentication privileges.
