Prior to version 0.3.2, an authorization bypass in tenant management endpoints of WeKnora application allows any authenticated user to read, modify, or delete any tenant by ID. Since account registration is open to the public, this vulnerability allows any unauthenticated attacker to register an account and subsequently exploit the system. This enables cross-tenant account takeover and destruction, making the impact critical. This issue has been patched in version 0.3.2.","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:H/A:H","score":8.8},"cwes":["CWE-284"],"references":["https://github.com/Tencent/WeKnora/security/advisories/GHSA-ccj6-79j6-cq5q"],"products":["tencent:weknora"],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-30855","score":0.00342,"percentile":0.27707,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-ccj6-79j6-cq5q","url":"https://osv.dev/vulnerability/GHSA-ccj6-79j6-cq5q","summary":"WeKnora Vulnerable to Broken Access Control in Tenant Management","modified":"2026-03-23T04:56:08.512052337Z","packages":[{"ecosystem":"Go","name":"github.com/Tencent/WeKnora","purl":"pkg:golang/github.com/Tencent/WeKnora","ranges":["<0.3.2"],"fixed":["0.3.2"]}]},{"id":"GO-2026-4642","url":"https://osv.dev/vulnerability/GO-2026-4642","summary":"WeKnora Vulnerable to Broken Access Control in Tenant Management in github.com/Tencent/WeKnora","modified":"2026-03-23T04:52:47.948131Z","packages":[{"ecosystem":"Go","name":"github.com/Tencent/WeKnora","purl":"pkg:golang/github.com/Tencent/WeKnora","ranges":["<0.3.1"],"fixed":["0.3.1"]}]}],"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).
