From version 0.4.0 to before version 0.5.0b3.dev97, the set_config_value() API endpoint allows users with the non-admin SETTINGS permission to modify any configuration option without restriction. The reconnect.script config option controls a file path that is passed directly to subprocess.run() in the thread manager's reconnect logic. A SETTINGS user can set this to any executable file on the system, achieving Remote Code Execution. The only validation in set_config_value() is a hardcoded check for general.storage_folder — all other security-critical settings including reconnect.script are writable without any allowlist or path restriction. This issue has been patched in version 0.5.0b3.dev97.","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:H","score":8.8},"cwes":["CWE-269"],"references":["https://github.com/pyload/pyload/security/advisories/GHSA-r7mc-x6x7-cqxx"],"products":["pyload-ng_project:pyload-ng","pyload:pyload"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-33509","score":0.0055,"percentile":0.46022,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-r7mc-x6x7-cqxx","url":"https://osv.dev/vulnerability/GHSA-r7mc-x6x7-cqxx","summary":"pyLoad SETTINGS Permission Users Can Achieve Remote Code Execution via Unrestricted Reconnect Script Configuration","modified":"2026-07-13T16:42:43.646337785Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":[">=0.4.0 <=0.5.0b3.dev96"],"fixed":[]}]},{"id":"PYSEC-2026-2996","url":"https://osv.dev/vulnerability/PYSEC-2026-2996","summary":"pyLoad SETTINGS Permission Users Can Achieve Remote Code Execution via Unrestricted Reconnect Script Configuration","modified":"2026-07-13T16:32:41.273266028Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":[">=0.4.0 <=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).
