Prior to version 0.2.12, a broken access control vulnerability in the database query tool allows any authenticated tenant to read sensitive data belonging to other tenants, including API keys, model configurations, and private messages. The application fails to enforce tenant isolation on critical tables (models, messages, embeddings), enabling unauthorized cross-tenant data access with user-level authentication privileges. This issue has been patched in version 0.2.12.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-284"],"references":["https://github.com/Tencent/WeKnora/security/advisories/GHSA-2f4c-vrjq-rcgv"],"products":["tencent:weknora"],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-30859","score":0.00221,"percentile":0.12727,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-2f4c-vrjq-rcgv","url":"https://osv.dev/vulnerability/GHSA-2f4c-vrjq-rcgv","summary":"WeKnora has Broken Access Control - Cross-Tenant Data Exposure","modified":"2026-03-23T04:55:59.451135921Z","packages":[{"ecosystem":"Go","name":"github.com/Tencent/WeKnora","purl":"pkg:golang/github.com/Tencent/WeKnora","ranges":["<0.2.12"],"fixed":["0.2.12"]}]},{"id":"GO-2026-4637","url":"https://osv.dev/vulnerability/GO-2026-4637","summary":"WeKnora has Broken Access Control - Cross-Tenant Data Exposure in github.com/Tencent/WeKnora","modified":"2026-03-23T04:52:47.828571Z","packages":[{"ecosystem":"Go","name":"github.com/Tencent/WeKnora","purl":"pkg:golang/github.com/Tencent/WeKnora","ranges":["all versions"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
