{"id":"CVE-2025-66470","aliases":["GHSA-2m4f-cg75-76w2","PYSEC-2026-1696"],"url":"https://o3.security/vulnerability/CVE-2025-66470","summary":"NiceGUI Stored/Reflected XSS in ui.interactive_image via unsanitized SVG content","details":"NiceGUI is a Python-based UI framework. Versions 3.3.1 and below are subject to a XSS vulnerability through the ui.interactive_image component of NiceGUI. The component renders SVG content using Vue's v-html directive without any sanitization. This allows attackers to inject malicious HTML or JavaScript via the SVG <foreignObject> tag whenever the image component is rendered or updated. This is particularly dangerous for dashboards or multi-user applications displaying user-generated content or annotations. This issue is fixed in version 3.4.0.","published":"2025-12-09T00:11:14.690Z","modified":"2026-08-08T03:48:05.875869386Z","cvss":{"score":6.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"nicegui","fixedVersion":"3.4.0"}],"fix":{"url":"https://github.com/zauberzeug/nicegui/commit/58ad0b36e19922de16bbc79ea3ddd29851b1a3e3","label":"zauberzeug/nicegui@58ad0b3"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/66xxx/CVE-2025-66470.json"},{"type":"ADVISORY","url":"https://github.com/zauberzeug/nicegui/security/advisories/GHSA-2m4f-cg75-76w2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-66470"},{"type":"FIX","url":"https://github.com/zauberzeug/nicegui/commit/58ad0b36e19922de16bbc79ea3ddd29851b1a3e3"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T03:48:05.875869386Z"}}
