An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-62862 exists.\n\nAffected product: baptisteArno typebot.io. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-62862/ (Markdown: https://insights.sbomify.com/CVE-2026-62862/index.md)","id":"CVE-2026-62862","markdown":"https://insights.sbomify.com/CVE-2026-62862/index.md","name":"CVE-2026-62862","record":{"aliases":["GHSA-4g76-cwmg-gqgw"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Chatbot builder","requires_auth":"none","summary":"An attacker can brute-force weak 6-digit magic-link codes to take over user accounts and access sensitive bot data in self-hosted Typebot instances.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-330","name":"Use of Insufficiently Random Values"},{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"Typebot is an open-source chatbot builder. In self-hosted versions up to and including 3.17.1, the default passwordless email magic-link authentication is vulnerable to login-code brute forcing that leads to account takeover. The email provider overrides NextAuth's default cryptographically secure token with a 6-digit code generated using Math.random(), reducing the keyspace to 900,000 with a 10-minute expiry, and the code itself is the raw value placed in the magic link. The verification callback enforces no attempt limit, lockout, or CSRF protection, and an incorrect guess does not consume the real code because the adapter returns null on a not-found token, so a valid code survives unlimited guessing within its lifetime. The only rate limiter applies to the code-sending path and is keyed on the client-controlled X-Forwarded-For header, allowing an attacker to request many concurrent live codes for one victim and further raise the odds of a matching guess. As a result, an anonymous attacker who knows a victim's email address can brute-force the callback and obtain an authenticated session as that user with no victim interaction, gaining full access to the victim's bots, results, and connected integration credentials. Deployments configured for OAuth or SSO only, with no email provider, are not affected.
