{"id":"CVE-2026-24766","aliases":["GHSA-95ff-46g6-6gw9"],"url":"https://o3.security/vulnerability/CVE-2026-24766","summary":"NocoDB Vulnerable to Prototype Pollution in Connection Test Endpoint, Leading to DoS","details":"NocoDB is software for building databases as spreadsheets. Prior to version 0.301.0, an authenticated user with org-level-creator permissions can exploit prototype pollution in the `/api/v2/meta/connection/test` endpoint, causing all database write operations to fail application-wide until server restart. While the pollution technically bypasses SUPER_ADMIN authorization checks, no practical privileged actions can be performed because database operations fail immediately after pollution. Version 0.301.0 patches the issue.","published":"2026-01-28T20:27:42.819Z","modified":"2026-08-07T11:31:07.943399734Z","cvss":{"score":4.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"nocodb","fixedVersion":"0.301.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/24xxx/CVE-2026-24766.json"},{"type":"ADVISORY","url":"https://github.com/nocodb/nocodb/security/advisories/GHSA-95ff-46g6-6gw9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-24766"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:07.943399734Z"}}
