{"id":"CVE-2026-34207","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-34207","generatedAt":"2026-10-28T03:25:53.829Z","title":"In versions prior to 3.16.0, SSRF protection for Webhook / HTTP Request blocks validates only the URL string, blocked hostname literals, and literal IP formats.","description":"TypeBot is a chatbot builder tool. In versions prior to 3.16.0, SSRF protection for Webhook / HTTP Request blocks validates only the URL string, blocked hostname literals, and literal IP formats. It does not resolve DNS before allowing the request. As a result, a hostname such as ssrf-repro.example that resolves to 127.0.0.1, 169.254.169.254, or RFC1918/private space passes validation and is later fetched by the backend HTTP client. This enables server-side request forgery to loopback, cloud metadata, and private network targets. This issue has been resolved in version 3.16.0.","published":"2026-05-22T17:16:47.000Z","lastModified":"2026-07-23T16:10:00.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":7.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L"},"cwe":["CWE-20","CWE-918"],"affected":[],"epss":{"score":0.00239,"percentile":0.14798,"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":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.24%).
