An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-80426 in the wild and no public exploit code.\n\nAffected product: voxel51 fiftyone. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-80426/ (Markdown: https://insights.sbomify.com/CVE-2026-80426/index.md)","id":"CVE-2026-80426","markdown":"https://insights.sbomify.com/CVE-2026-80426/index.md","name":"CVE-2026-80426","record":{"aliases":["GHSA-q8rv-hw8g-gww7"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"FiftyOne data tool","requires_auth":"none","summary":"Attackers can inject scripts via dataset field descriptions, leading to code execution and local file access in FiftyOne.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"FiftyOne before 1.21.0 Stored Cross-Site Scripting via Unescaped Field Description","id":"CVE-2026-80426","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"bestzip before 2.2.6 and 3.0.x before 3.0.2 Argument Injection via Missing Option Delimiter","id":"CVE-2026-80427"},"packages":[],"prev":{"headline":"DataStage on Cloud Pak for Data has several vulnerabilities","id":"CVE-2026-80425"},"products":["fiftyone"],"published":"2026-08-26","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-08-29","vendors":["voxel51"]},"summary":"Attackers can inject scripts via dataset field descriptions, leading to code execution and local file access in FiftyOne.","url":"https://insights.sbomify.com/CVE-2026-80426/"}
