An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-25732 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nicegui (PyPI): affected all versions; fixed in 3.7.0\n- nicegui (PyPI): affected all versions; fixed in 3.7.0\n- nicegui (PyPI): affected all versions; fixed in 3.7.0\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-2026-25732/ (Markdown: https://insights.sbomify.com/CVE-2026-25732/index.md)","id":"CVE-2026-25732","markdown":"https://insights.sbomify.com/CVE-2026-25732/index.md","name":"CVE-2026-25732","record":{"aliases":["GHSA-9ffm-fxg3-xrhh","PYSEC-2026-95"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Python UI framework","requires_auth":"none","summary":"Attackers can write arbitrary files outside intended directories via unsanitized filenames in NiceGUI, potentially leading to remote code execution.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"nicegui","vendor":"zauberzeug"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"NiceGUI is a Python-based UI framework. Prior to 3.7.0, NiceGUI's FileUpload.name property exposes client-supplied filename metadata without sanitization, enabling path traversal when developers use the pattern UPLOAD_DIR / file.name. Malicious filenames containing ../ sequences allow attackers to write files outside intended directories, with potential for remote code execution through application file overwrites in vulnerable deployment patterns. This design creates a prevalent security footgun affecting applications following common community patterns. Note: Exploitation requires application code incorporating file.name into filesystem paths without sanitization. Applications using fixed paths, generated filenames, or explicit sanitization are not affected. This vulnerability is fixed in 3.7.0.","ecosystems":["PyPI"],"exploits":{"exploitdb":1,"first_seen":"2026-02-08","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-02-08T10:18:51Z","kind":"github_poc","ref":"https://github.com/mbanyamer/CVE-2026-25732-NiceGUI-3.6.1","stars":0,"title":null},{"date":"2026-04-30","kind":"exploitdb","ref":"52534","stars":null,"title":"NiceGUI 3.6.1 - Path Traversal"}],"tier":"poc_unverified"},"has_fix":true,"headline":"NiceGUI's Path Traversal via Unsanitized FileUpload.name Enables Arbitrary File Write","id":"CVE-2026-25732","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":3,"n_references":3,"next":{"headline":"Rucio WebUI Vulnerable to Stored Cross-site Scripting (XSS) through Custom Rule Function","id":"CVE-2026-25733"},"packages":[{"ecosystem":"PyPI","fixed":["3.7.0"],"introduced":["0"],"last_affected":[],"package":"nicegui","purl":null,"source":"GHSA-9ffm-fxg3-xrhh"},{"ecosystem":"PyPI","fixed":["3.7.0"],"introduced":["0"],"last_affected":[],"package":"nicegui","purl":"pkg:pypi/nicegui","source":"GHSA-9ffm-fxg3-xrhh"},{"ecosystem":"PyPI","fixed":["3.7.0"],"introduced":["0"],"last_affected":[],"package":"nicegui","purl":"pkg:pypi/nicegui","source":"PYSEC-2026-95"}],"prev":{"headline":"Calibre Affected by Arbitrary Code Execution via Server-Side Template Injection in Calibre HTML Export","id":"CVE-2026-25731"},"products":["nicegui"],"published":"2026-02-06","related":[{"cvss_score":7.5,"headline":"NiceGUI Path Traversal Vulnerability in app.add_media_files() Allows Arbitrary File Reading","id":"CVE-2025-66645","kev_date_added":null,"published":"2025-12-09"},{"cvss_score":7.2,"headline":"Zero-click XSS in all NiceGUI apps which uses `ui.sub_pages`","id":"CVE-2026-21873","kev_date_added":null,"published":"2026-01-08"},{"cvss_score":6.9,"headline":"NiceGUI's unvalidated chunk size parameter in media routes can cause memory exhaustion","id":"CVE-2026-33332","kev_date_added":null,"published":"2026-03-24"},{"cvss_score":6.1,"headline":"NiceGUI has XSS via Code Injection","id":"CVE-2026-27156","kev_date_added":null,"published":"2026-02-24"},{"cvss_score":6.1,"headline":"NiceGUI's XSS vulnerability in ui.markdown() allows arbitrary JavaScript execution through unsanitized HTML content","id":"CVE-2026-25516","kev_date_added":null,"published":"2026-02-06"},{"cvss_score":6.1,"headline":"NiceGUI is vulnerable to XSS via Unescaped URL in ui.navigate.history.push() / replace()","id":"CVE-2026-21871","kev_date_added":null,"published":"2026-01-08"}],"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":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-02-09","vendors":["zauberzeug"]},"summary":"Attackers can write arbitrary files outside intended directories via unsanitized filenames in NiceGUI, potentially leading to remote code execution.","url":"https://insights.sbomify.com/CVE-2026-25732/"}
