Attackers can rename worksheet sheets in imported files such as XLSX, ODS, XLS, or YAML with script payloads that are assigned to the Dataset title attribute and rendered unescaped inside an HTML h3 tag, leading to session hijacking, unauthorized administrative actions, and sensitive data exposure when the output is rendered in a browser.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","score":4.8},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4},"cwes":["CWE-79"],"references":["https://github.com/jazzband/tablib","https://github.com/jazzband/tablib/pull/668","https://github.com/jazzband/tablib/releases/tag/v3.10.0","https://www.vulncheck.com/advisories/tablib-versions-prior-to-stored-xss-via-html-export-dataset-title"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:35.584907681+00:00"},"epss":{"cve":"CVE-2026-9318","score":0.00298,"percentile":0.22308,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-gqgw-jghv-mxwx","url":"https://osv.dev/vulnerability/GHSA-gqgw-jghv-mxwx","summary":"tablib: Stored XSS in the HTML export via unescaped dataset title","modified":"2026-09-10T03:51:14.092730335Z","packages":[{"ecosystem":"PyPI","name":"tablib","purl":"pkg:pypi/tablib","ranges":["<3.10.0"],"fixed":["3.10.0"]}]},{"id":"PYSEC-2026-3702","url":"https://osv.dev/vulnerability/PYSEC-2026-3702","summary":"tablib: Stored XSS in the HTML export via unescaped dataset title","modified":"2026-08-19T12:45:07.048785846Z","packages":[{"ecosystem":"PyPI","name":"tablib","purl":"pkg:pypi/tablib","ranges":["<3.10.0"],"fixed":["3.10.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
