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.","published":"2026-08-11T17:17:59.237","modified":"2026-08-11T17:17:59.237","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/baptisteArno/typebot.io/commit/6f915c3096bd43d4a913f0f2c7a92e8463f81a86","label":"baptisteArno/typebot.io@6f915c3"},"references":[{"type":"WEB","url":"https://github.com/baptisteArno/typebot.io/commit/6f915c3096bd43d4a913f0f2c7a92e8463f81a86"},{"type":"WEB","url":"https://github.com/baptisteArno/typebot.io/pull/2494"},{"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-h67g-6q6g-58cj"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-11T17:17:59.237"}}
