In versions 0.5.0b3.dev89 and below, there is an opportunity for path traversal in pyLoad-ng CNL Blueprint via package parameter, allowing Arbitrary File Write which leads to Remote Code Execution (RCE). The addcrypted endpoint in pyload-ng suffers from an unsafe path construction vulnerability, allowing unauthenticated attackers to write arbitrary files outside the designated storage directory. This can be abused to overwrite critical system files, including cron jobs and systemd services, leading to privilege escalation and remote code execution as root. This issue is fixed in version 0.5.0b3.dev90.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-22"],"references":["https://github.com/pyload/pyload/commit/70a44fe02c03bce92337b5d370d2a45caa4de3d4","https://github.com/pyload/pyload/pull/4596","https://github.com/pyload/pyload/security/advisories/GHSA-48rp-jc79-2264","https://github.com/pyload/pyload/security/advisories/GHSA-48rp-jc79-2264"],"products":["pyload-ng_project:pyload-ng"],"source":"nvd","synced_at":"2026-10-19T22:06:45.861874017+00:00"},"epss":{"cve":"CVE-2025-54802","score":0.01294,"percentile":0.70314,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-48rp-jc79-2264","url":"https://osv.dev/vulnerability/GHSA-48rp-jc79-2264","summary":"pyLoad CNL Blueprint allows Path Traversal through `dlc_path` which leads to Remote Code Execution (RCE)","modified":"2026-09-10T03:50:26.651259719Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<0.5.0b3.dev90"],"fixed":["0.5.0b3.dev90"]}]},{"id":"PYSEC-2026-493","url":"https://osv.dev/vulnerability/PYSEC-2026-493","summary":"pyLoad CNL Blueprint allows Path Traversal through `dlc_path` which leads to Remote Code Execution (RCE)","modified":"2026-07-13T16:15:33.397718613Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<0.5.0b3.dev90"],"fixed":["0.5.0b3.dev90"]}]}],"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).
