Prior to 3.18.0, any authenticated non-guest workspace member can remove another workspace's public custom domain and make typebots on that domain unavailable. The custom-domain delete handler in handleDeleteCustomDomain.ts authorizes a caller against a client-supplied workspaceId but sends the client-supplied domain name to the shared Vercel project before verifying that the domain belongs to that workspace. This issue is fixed in version 3.18.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:N/SI:H/SA:H","score":6.4},"cvss_v3":null,"cwes":["CWE-639","CWE-862"],"references":["https://github.com/baptisteArno/typebot.io/commit/06575dfcd461ba76071012869d4b1f4046f9a6b8","https://github.com/baptisteArno/typebot.io/releases/tag/v3.18.0","https://github.com/baptisteArno/typebot.io/security/advisories/GHSA-7h82-p425-wpmg"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:17.453294893+00:00"},"epss":{"cve":"CVE-2026-62861","score":0.00414,"percentile":0.35672,"date":"2026-10-31"},"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).
