{"id":"CVE-2026-48494","state":"PUBLISHED","title":"TypeBot vulnerable to cross-typebot WhatsApp preview webhook resume via global `wa-preview-{phone}` session ids","description":"TypeBot is a chatbot builder tool. In version 3.16.1, an authenticated user who has read access to any typebot can resume a WhatsApp preview webhook session that belongs to a different typebot by mixing an authorized `typebotId` and `blockId` and a foreign preview phone number tied to another preview session. The WhatsApp test-webhook handler authorizes the parent typebot first, but then resolves the preview chat session only by `wa-preview-{phone}`. As a result, an attacker can inject arbitrary webhook JSON into another workspace's WhatsApp preview session and advance its draft/unpublished flow without any access to the victim typebot. Version 3.17.0 patches the issue.","publishedAt":"2026-08-11T17:09:33.029Z","updatedAt":"2026-08-11T19:04:18.053Z","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":"= 3.16.1","status":"affected"}]}],"references":["https://github.com/baptisteArno/typebot.io/security/advisories/GHSA-fqf7-mmp5-j3jq","https://github.com/baptisteArno/typebot.io/pull/2499","https://github.com/baptisteArno/typebot.io/commit/36a618610174fd168fb255d9c8ecc0d2cf61a192","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-2026-48494.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-48494","state":"PUBLISHED","datePublished":"2026-08-11T17:09:33.029Z","dateUpdated":"2026-08-11T19:04:18.053Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-21T15:33:08.292Z"},"containers":{"cna":{"title":"TypeBot vulnerable to cross-typebot WhatsApp preview webhook resume via global `wa-preview-{phone}` session ids","descriptions":[{"lang":"en","value":"TypeBot is a chatbot builder tool.
