In 0.5.0b3.dev96 and earlier, the parse_urls API function in src/pyload/core/api/__init__.py fetches arbitrary URLs server-side via get_url(url) (pycurl) without any URL validation, protocol restriction, or IP blacklist. An authenticated user with ADD permission can make HTTP/HTTPS requests to internal network resources and cloud metadata endpoints, read local files via file:// protocol (pycurl reads the file server-side), interact with internal services via gopher:// and dict:// protocols, and enumerate file existence via error-based oracle (error 37 vs empty response).","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","score":7.7},"cwes":["CWE-918"],"references":["https://github.com/pyload/pyload/commit/4032e57d61d8f864e39f4dcfdb567527a50a9e1f","https://github.com/pyload/pyload/security/advisories/GHSA-2wvg-62qm-gj33","https://github.com/pyload/pyload/security/advisories/GHSA-2wvg-62qm-gj33"],"products":["pyload-ng_project:pyload-ng"],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-35187","score":0.00269,"percentile":0.19074,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-2wvg-62qm-gj33","url":"https://osv.dev/vulnerability/GHSA-2wvg-62qm-gj33","summary":"pyLoad: SSRF in parse_urls API endpoint via unvalidated URL parameter","modified":"2026-07-13T16:42:32.681674093Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<=0.5.0b3.dev96"],"fixed":[]}]},{"id":"PYSEC-2026-2988","url":"https://osv.dev/vulnerability/PYSEC-2026-2988","summary":"pyLoad: SSRF in parse_urls API endpoint via unvalidated URL parameter","modified":"2026-07-13T16:31:59.834581264Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<=0.5.0b3.dev96"],"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).
