{"id":"CVE-2026-48765","state":"PUBLISHED","title":"TypeBot vulnerable to cross-workspace OAuth credential takeover in updateOAuthCredentials via missing object binding","description":"TypeBot is a chatbot builder tool. Versions prior to 3.17.0 allow a low-privilege read collaborator to extract a workspace OAuth `credentialsId` from a readable bot configuration and then overwrite that credential through `handleUpdateOAuthCredentials()` by supplying an attacker-controlled writable `workspaceId`. The update path validates only the attacker-supplied workspace and then updates the credential record by global `id` alone, while also rewriting the credential's `workspaceId`. This allows cross-workspace OAuth credential takeover and reassignment. Version 3.17.0 patches the issue.","publishedAt":"2026-08-11T20:37:48.115Z","updatedAt":"2026-08-12T12:53:42.764Z","severity":{"score":9.9,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["baptisteArno typebot.io"],"affected":[{"vendor":"baptisteArno","product":"typebot.io","versions":[{"version":"< 3.17.0","status":"affected"}]}],"references":["https://github.com/baptisteArno/typebot.io/security/advisories/GHSA-3788-7276-x4j4","https://github.com/baptisteArno/typebot.io/pull/2459","https://github.com/baptisteArno/typebot.io/commit/7ae4c007d0987d2ca907b47e1b7418db62b8a157","https://github.com/baptisteArno/typebot.io/releases/tag/v3.17.0"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/48xxx/CVE-2026-48765.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-48765","state":"PUBLISHED","datePublished":"2026-08-11T20:37:48.115Z","dateUpdated":"2026-08-12T12:53:42.764Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-22T19:39:05.356Z"},"containers":{"cna":{"title":"TypeBot vulnerable to cross-workspace OAuth credential takeover in updateOAuthCredentials via missing object binding","descriptions":[{"lang":"en","value":"TypeBot is a chatbot builder tool.
