It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-46343 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- n8n (npm): affected all versions; fixed in 1.90.0\n- n8n (npm): affected all versions; fixed in 1.90.0\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-2025-46343/ (Markdown: https://insights.sbomify.com/CVE-2025-46343/index.md)","id":"CVE-2025-46343","markdown":"https://insights.sbomify.com/CVE-2025-46343/index.md","name":"CVE-2025-46343","record":{"aliases":["GHSA-c8hm-hr8h-5xjw"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"n8n workflow automation","requires_auth":"low_privilege","summary":"An authenticated attacker can upload malicious HTML files to trigger stored XSS, potentially leading to account takeover of other users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"n8n","vendor":"n8n"}],"cvss":{"score":5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"n8n is a workflow automation platform. Prior to version 1.90.0, n8n is vulnerable to stored cross-site scripting (XSS) through the attachments view endpoint. n8n workflows can store and serve binary files, which are accessible to authenticated users. However, there is no restriction on the MIME type of uploaded files, and the MIME type could be controlled via a GET parameter. This allows the server to respond with any MIME type, potentially enabling malicious content to be interpreted and executed by the browser. An authenticated attacker with member-level permissions could exploit this by uploading a crafted HTML file containing malicious JavaScript. When another user visits the binary data endpoint with the MIME type set to text/html, the script executes in the context of the user’s session. This script could send a request to change the user’s email address in their account settings, effectively enabling account takeover. This issue has been patched in version 1.90.0.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"n8n Vulnerable to Stored XSS through Attachments View Endpoint","id":"CVE-2025-46343","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":"n8n:n8n","products":["n8n:n8n"],"type":"xss","year":"2025"},"n_packages":2,"n_references":4,"next":{"headline":"Auth0 NextJS SDK v4 Missing Session Invalidation","id":"CVE-2025-46344"},"packages":[{"ecosystem":"npm","fixed":["1.90.0"],"introduced":["0"],"last_affected":[],"package":"n8n","purl":null,"source":"GHSA-c8hm-hr8h-5xjw"},{"ecosystem":"npm","fixed":["1.90.0"],"introduced":["0"],"last_affected":[],"package":"n8n","purl":"pkg:npm/n8n","source":"GHSA-c8hm-hr8h-5xjw"}],"prev":{"headline":"Kyverno vulnerable to bypass of policy rules that use namespace selectors in match statements","id":"CVE-2025-46342"},"products":["n8n"],"published":"2025-04-29","related":[{"cvss_score":10,"headline":"n8n Improper Control of Dynamically-Managed Code Resources","id":"CVE-2025-68613","kev_date_added":"2026-03-11","published":"2025-12-19"},{"cvss_score":10,"headline":"n8n is vulnerable to Remote Code Execution via Arbitrary File Write","id":"CVE-2026-21877","kev_date_added":null,"published":"2026-01-08"},{"cvss_score":10,"headline":"n8n Vulnerable to Unauthenticated File Access via Improper Webhook Request Handling","id":"CVE-2026-21858","kev_date_added":null,"published":"2026-01-07"},{"cvss_score":9.9,"headline":"n8n Unsafe Workflow Expression Evaluation Allows Remote Code Execution","id":"CVE-2026-1470","kev_date_added":null,"published":"2026-01-27"},{"cvss_score":9.9,"headline":"n8n Vulnerable to Arbitrary Command Execution in Pyodide based Python Code Node","id":"CVE-2025-68668","kev_date_added":null,"published":"2025-12-26"},{"cvss_score":9.5,"headline":"n8n has Unauthenticated Expression Evaluation via Form Node","id":"CVE-2026-27493","kev_date_added":null,"published":"2026-02-25"},{"cvss_score":9.4,"headline":"n8n: HTTP Request Node Pagination Prototype Pollution to RCE","id":"CVE-2026-44789","kev_date_added":null,"published":"2026-06-23"}],"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":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-29","vendors":["n8n-io"]},"summary":"An authenticated attacker can upload malicious HTML files to trigger stored XSS, potentially leading to account takeover of other users.","url":"https://insights.sbomify.com/CVE-2025-46343/"}
