CVE-2026-80426

Περιγραφή

FiftyOne renders a dataset field-s description as markup. The sidebar field-information component at app/packages/core/src/components/FieldLabelAndInfo/index.tsx passes the description string to React-s dangerouslySetInnerHTML, and no layer between storage and render escapes or sanitises it; the neighbouring info values in the same component are rendered as React children and are escaped, so the description is the only raw path. A description is free-form text held in the dataset schema, so it persists in the database and travels with an exported or published dataset. Opening a dataset obtained from another party and hovering the field runs the stored markup in the application-s origin. That origin is shared with the FiftyOne server, whose media route returns the contents of a caller-named absolute path and which is unauthenticated in the open-source server, so the injected script can read local files and reach the dataset and operator endpoints as the viewing user.
