Attackers can send crafted GET requests with path traversal segments targeting a prefix-matching sibling directory on disk, bypassing the directory containment check because Flask's path converter and Werkzeug's WSGI layer preserve the traversal segments while the resolved path still satisfies the flawed startswith comparison, enabling unauthorized file access outside the intended library directory.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-22"],"references":["https://github.com/Avaiga/taipy/commit/129fd407ffca49ee4ab853772c88d0c873e038dd","https://github.com/Avaiga/taipy/issues/2868","https://github.com/Avaiga/taipy/pull/2871","https://www.vulncheck.com/advisories/taipy-path-traversal-via-elementlibrary-get-resource","https://github.com/Avaiga/taipy/issues/2868"],"products":[],"source":"nvd","synced_at":"2026-10-26T12:35:18.182177120+00:00"},"epss":{"cve":"CVE-2026-48544","score":0.0052,"percentile":0.43872,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-28gh-q3gw-pvx8","url":"https://osv.dev/vulnerability/GHSA-28gh-q3gw-pvx8","summary":"Taipy contains a path traversal vulnerability","modified":"2026-07-13T16:43:52.476579605Z","packages":[{"ecosystem":"PyPI","name":"taipy","purl":"pkg:pypi/taipy","ranges":["<=4.1.1"],"fixed":[]}]},{"id":"PYSEC-2026-3081","url":"https://osv.dev/vulnerability/PYSEC-2026-3081","summary":"Taipy contains a path traversal vulnerability","modified":"2026-07-13T16:32:44.938853320Z","packages":[{"ecosystem":"PyPI","name":"taipy","purl":"pkg:pypi/taipy","ranges":["<=4.1.1"],"fixed":[]}]}],"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).
