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.","published":"2026-08-11T21:17:36.947","modified":"2026-08-11T21:17:36.947","cvss":{"score":9.9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/baptisteArno/typebot.io/commit/7ae4c007d0987d2ca907b47e1b7418db62b8a157","label":"baptisteArno/typebot.io@7ae4c00"},"references":[{"type":"WEB","url":"https://github.com/baptisteArno/typebot.io/commit/7ae4c007d0987d2ca907b47e1b7418db62b8a157"},{"type":"WEB","url":"https://github.com/baptisteArno/typebot.io/pull/2459"},{"type":"WEB","url":"https://github.com/baptisteArno/typebot.io/releases/tag/v3.17.0"},{"type":"WEB","url":"https://github.com/baptisteArno/typebot.io/security/advisories/GHSA-3788-7276-x4j4"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-11T21:17:36.947"}}
