Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-39970 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-2026-39970/ (Markdown: https://insights.sbomify.com/CVE-2026-39970/index.md)","id":"CVE-2026-39970","markdown":"https://insights.sbomify.com/CVE-2026-39970/index.md","name":"CVE-2026-39970","record":{"aliases":["GHSA-jj87-c343-26vp"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Chatbot builder tool","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary JavaScript in victims' browsers by uploading malicious SVG files, leading to session theft and account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"TypeBot is a chatbot builder tool. Versions 3.15.2 and prior contain a critical stored XSS vulnerability in the app.typebot.io profile picture upload form. The application fails to sanitize or restrict SVG/XML-based uploads and directly renders them when accessed through the domain. By uploading a crafted malicious SVG file containing embedded JavaScript, an attacker will execute arbitrary JavaScript code. This vulnerability directly enables stored XSS exploitation because the payload is persistently stored on your infrastructure (app.typebot.io) and accessible from a public-facing, permanent link. Stored XSS via malicious SVG uploads to app.typebot.io allows attackers to execute arbitrary JavaScript in victims' browsers, enabling session/token theft, account takeover, and exfiltration of sensitive user data. This issue has been fixed in version 3.16.0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"TypeBot: Stored Cross-Site Scripting (XSS) via SVG File Upload On Profile Picture Form","id":"CVE-2026-39970","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Serendipity: Host Header Injection leads to SMTP header injection via unvalidated HTTP_HOST","id":"CVE-2026-39971"},"packages":[],"prev":{"headline":"TypeBot: WhatsApp Webhook Endpoint Missing Signature Verification","id":"CVE-2026-39969"},"products":["typebot.io"],"published":"2026-05-22","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-22","vendors":["baptisteArno"]},"summary":"Attackers can execute arbitrary JavaScript in victims' browsers by uploading malicious SVG files, leading to session theft and account takeover.","url":"https://insights.sbomify.com/CVE-2026-39970/"}
