{"id":"CVE-2026-35187","summary":"pyLoad has SSRF in parse_urls API endpoint via unvalidated URL parameter","details":"pyLoad is a free and open-source download manager written in Python. 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).","aliases":["GHSA-2wvg-62qm-gj33"],"modified":"2026-07-08T08:12:58.672138304Z","published":"2026-04-06T19:33:06.557Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35187.json","unresolved_ranges":[{"extracted_events":[{"last_affected":"0.5.0b3.dev96"}],"source":"AFFECTED_FIELD"}],"cwe_ids":["CWE-918"],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35187.json"},{"type":"ADVISORY","url":"https://github.com/pyload/pyload/security/advisories/GHSA-2wvg-62qm-gj33"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35187"},{"type":"FIX","url":"https://github.com/pyload/pyload/commit/4032e57d61d8f864e39f4dcfdb567527a50a9e1f"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pyload/pyload","events":[{"introduced":"0"},{"fixed":"4032e57d61d8f864e39f4dcfdb567527a50a9e1f"}],"database_specific":{"source":"REFERENCES"}}],"versions":["v0.4.9","v0.4.8","v0.4.7","v0.4.6","v0.4.5","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4","v0.3.2","v0.3.1","v0.3","v0.2.2","v0.2.1","v0.2","v0.1.1","v0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-35187.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"}]}
