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-2026-28445 exists.\n\nAffected packages and fixed versions:\n- @typebot.io/js (npm): affected all versions; fixed in 0.10.1\n- @typebot.io/js (npm): affected all versions; fixed in 0.10.1\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-2026-28445/ (Markdown: https://insights.sbomify.com/CVE-2026-28445/index.md)","id":"CVE-2026-28445","markdown":"https://insights.sbomify.com/CVE-2026-28445/index.md","name":"CVE-2026-28445","record":{"aliases":["GHSA-6m7c-xfhp-p9fh"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Chatbot builder tool","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary JavaScript in the Typebot builder via unsanitized SVG icons, leading to session hijacking and privilege escalation.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Typebot is a chatbot builder tool. In versions 3.15.2 and prior, the RatingButton component in the embed package renders the user-controlled customIcon.svg field directly via Solid's innerHTML directive without any sanitization, even though DOMPurify is already a dependency and is used elsewhere in the codebase (e.g., StreamingBubble.tsx). Because rating blocks are not flagged as isUnsafe by the import sanitizer and the builder preview renders bots inline on the builder's own origin (builder.typebot.io) under a CSP permitting 'unsafe-inline', a malicious imported or collaborator-crafted typebot can execute arbitrary HTML/JS in the builder's authenticated context, bypassing the Web Worker sandbox that protects Script blocks during preview. This allows session hijacking and privilege escalation within the builder application. This issue has been fixed in version 3.16.0.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Typebot: Stored XSS via Rating Block Custom Icon Bypasses isUnsafe Sandbox in Builder Preview","id":"CVE-2026-28445","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":2,"n_references":3,"next":{"headline":"OpenClaw \u003c 2026.2.1 - Inbound Allowlist Policy Bypass in voice-call Extension via Empty Caller ID and Suffix Matching","id":"CVE-2026-28446"},"packages":[{"ecosystem":"npm","fixed":["0.10.1"],"introduced":["0"],"last_affected":[],"package":"@typebot.io/js","purl":null,"source":"GHSA-6m7c-xfhp-p9fh"},{"ecosystem":"npm","fixed":["0.10.1"],"introduced":["0"],"last_affected":[],"package":"@typebot.io/js","purl":"pkg:npm/%40typebot.io/js","source":"GHSA-6m7c-xfhp-p9fh"}],"prev":{"headline":"Typebot: IDOR in Result Logs Endpoint Allows Cross-Workspace Data Disclosure","id":"CVE-2026-28444"},"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":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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 the Typebot builder via unsanitized SVG icons, leading to session hijacking and privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-28445/"}
