{"id":"CVE-2026-39966","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-39966","generatedAt":"2026-10-28T00:28:18.601Z","title":"TypeBot is a chatbot builder tool.","description":"TypeBot is a chatbot builder tool. In versions 3.15.2, the getLinkedTypebots API endpoint returns full bot definitions to any authenticated user who references a target bot ID in a Typebot Link block, regardless of workspace ownership, leading to IDOR. The authorization check uses Array.filter() with an async callback — since filter() is synchronous, the callback always returns a truthy Promise, so the access control predicate is never actually evaluated. Any authenticated Typebot user can read the full definition of any other workspace's private bots, including: all conversation blocks and logic flow, variable values embedded in the bot (credentials, API keys, PII), webhook URLs and integration configurations. This issue has been fixed in version 3.16.0.","published":"2026-05-22T19:17:03.000Z","lastModified":"2026-07-23T16:10:00.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-863"],"affected":[],"epss":{"score":0.00256,"percentile":0.17083,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.26%).
