{"cve":"CVE-2026-48494","nvd":{"published":"2026-08-11T18:17:33.310","modified":"2026-10-23T19:10:00.167","status":"Deferred","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an attacker can inject arbitrary webhook JSON into another workspace's WhatsApp preview session and advance its draft/unpublished flow without any access to the victim typebot.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.","cvss_v4":{"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","score":7.1},"cvss_v3":null,"cwes":["CWE-639"],"references":["https://github.com/baptisteArno/typebot.io/commit/36a618610174fd168fb255d9c8ecc0d2cf61a192","https://github.com/baptisteArno/typebot.io/pull/2499","https://github.com/baptisteArno/typebot.io/releases/tag/v3.17.0","https://github.com/baptisteArno/typebot.io/security/advisories/GHSA-fqf7-mmp5-j3jq","https://github.com/baptisteArno/typebot.io/security/advisories/GHSA-fqf7-mmp5-j3jq"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:35.584907681+00:00"},"epss":{"cve":"CVE-2026-48494","score":0.00465,"percentile":0.39993,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
