{"cve":"CVE-2026-42313","nvd":{"published":"2026-05-11T18:16:34.980","modified":"2026-06-17T10:47:40.737","status":"Analyzed","description":"pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev100, the set_config_value() API method (@permission(Perms.SETTINGS)) in src/pyload/core/api/__init__.py gates security-sensitive options behind a hand-maintained allowlist ADMIN_ONLY_CORE_OPTIONS. The allowlist contains (\"proxy\", \"username\") and (\"proxy\", \"password\") — which protect the proxy credentials — but it does not include (\"proxy\", \"enabled\"), (\"proxy\", \"host\"), (\"proxy\", \"port\"), or (\"proxy\", \"type\"). Any authenticated user with the non-admin SETTINGS permission can enable proxying and point pyload at any host they control. From that point, every outbound download, captcha fetch, update check, and plugin HTTP call is transparently routed through the attacker. This is a direct continuation of the fix family CVE-2026-33509 / CVE-2026-35463 / CVE-2026-35464 / CVE-2026-35586, each of which patched a different missed option in the same allowlist. This vulnerability is fixed in 0.5.0b3.dev100.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L","score":8.3},"cwes":["CWE-441","CWE-863","CWE-918"],"references":["https://github.com/pyload/pyload/security/advisories/GHSA-pg67-9wjv-mr85","https://github.com/pyload/pyload/security/advisories/GHSA-pg67-9wjv-mr85"],"products":["pyload-ng_project:pyload-ng"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-42313","score":0.00396,"percentile":0.33785,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-pg67-9wjv-mr85","url":"https://osv.dev/vulnerability/GHSA-pg67-9wjv-mr85","summary":"pyload-ng: non-admin SETTINGS users can redirect all outbound traffic through an attacker-controlled proxy via unrestricted `proxy.*` config (incomplete fix for CVE-2026-33509 / -35463 / -35464 / -35586)","modified":"2026-06-08T20:00:12.395532434Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<0.5.0b3.dev100"],"fixed":["0.5.0b3.dev100"]}]},{"id":"PYSEC-2026-127","url":"https://osv.dev/vulnerability/PYSEC-2026-127","summary":"","modified":"2026-05-20T09:19:16.010199Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<0.5.0b3.dev100"],"fixed":["0.5.0b3.dev100"]}]}],"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).
