This vulnerability can be exploited by sending a POST request with an excessively large payload, potentially leading to server resource exhaustion and denial of service (DoS). Additionally, unauthorized users can misuse the endpoint to generate PDFs without verification, resulting in service misuse and potential operational and financial impacts.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","score":8.2},"cwes":["CWE-306"],"references":["https://huntr.com/bounties/ebe8c1fa-113b-4df9-be03-a406b9adb9f4","https://huntr.com/bounties/ebe8c1fa-113b-4df9-be03-a406b9adb9f4"],"products":["openwebui:open_webui"],"source":"nvd","synced_at":"2026-10-19T22:00:17.429720821+00:00"},"epss":{"cve":"CVE-2024-8053","score":0.00652,"percentile":0.51249,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-9vf8-xgwm-97r8","url":"https://osv.dev/vulnerability/GHSA-9vf8-xgwm-97r8","summary":"Open WebUI lacks authentication for the `api/v1/utils/pdf` endpoint","modified":"2026-07-07T17:56:37.595056753Z","packages":[{"ecosystem":"PyPI","name":"open-webui","purl":"pkg:pypi/open-webui","ranges":["<=0.3.10"],"fixed":[]}]},{"id":"PYSEC-2026-1725","url":"https://osv.dev/vulnerability/PYSEC-2026-1725","summary":"Open WebUI lacks authentication for the `api/v1/utils/pdf` endpoint","modified":"2026-07-23T11:45:10.961063946Z","packages":[{"ecosystem":"PyPI","name":"open-webui","purl":"pkg:pypi/open-webui","ranges":["<0.5.13"],"fixed":["0.5.13"]}]}],"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).
