{"id":"CVE-2026-47704","state":"PUBLISHED","title":"TypeBot vulnerable to cross-typebot webhook resume via unchecked `resultId` lineage allows unauthorized control of another bot's waiting session","description":"TypeBot is a chatbot builder tool. Prior to version 3.17.0, an authenticated user who has read access to any typebot can resume a waiting webhook session that belongs to a different typebot by mixing an authorized `typebotId` and `blockId` and a foreign live `resultId`. The webhook resume handler authorizes the parent typebot first, but then resolves the descendant `result` only by `resultId`. As a result, an attacker can inject arbitrary webhook JSON into another typebot's suspended session and advance its execution without any access to the victim typebot. Version 3.17.0 patches the issue.","publishedAt":"2026-08-11T16:23:07.988Z","updatedAt":"2026-08-12T22:13:56.717Z","severity":{"score":7.1,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","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-h67g-6q6g-58cj","https://github.com/baptisteArno/typebot.io/pull/2494","https://github.com/baptisteArno/typebot.io/commit/6f915c3096bd43d4a913f0f2c7a92e8463f81a86","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/2026/47xxx/CVE-2026-47704.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-47704","state":"PUBLISHED","datePublished":"2026-08-11T16:23:07.988Z","dateUpdated":"2026-08-12T22:13:56.717Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-19T21:18:20.404Z"},"containers":{"cna":{"title":"TypeBot vulnerable to cross-typebot webhook resume via unchecked `resultId` lineage allows unauthorized control of another bot's waiting session","descriptions":[{"lang":"en","value":"TypeBot is a chatbot builder tool.
