{"cve":"CVE-2026-35592","nvd":{"published":"2026-04-07T17:16:34.280","modified":"2026-06-17T10:40:49.740","status":"Analyzed","description":"pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev97, the _safe_extractall() function in src/pyload/plugins/extractors/UnTar.py uses os.path.commonprefix() for its path traversal check, which performs character-level string comparison rather than path-level comparison. This allows a specially crafted tar archive to write files outside the intended extraction directory. The correct function os.path.commonpath() was added to the codebase in the CVE-2026-32808 fix (commit 5f4f0fa) but was never applied to _safe_extractall(), making this an incomplete fix. This vulnerability is fixed in 0.5.0b3.dev97.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","score":6.5},"cwes":["CWE-22"],"references":["https://github.com/pyload/pyload/security/advisories/GHSA-mvwx-582f-56r7"],"products":["pyload-ng_project:pyload-ng"],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-35592","score":0.00255,"percentile":0.17156,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-mvwx-582f-56r7","url":"https://osv.dev/vulnerability/GHSA-mvwx-582f-56r7","summary":"pyload-ng: Incomplete Tar Path Traversal Fix in UnTar._safe_extractall via os.path.commonprefix Bypass","modified":"2026-06-08T20:00:10.712797819Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<0.5.0b3.dev97"],"fixed":["0.5.0b3.dev97"]}]},{"id":"PYSEC-2026-124","url":"https://osv.dev/vulnerability/PYSEC-2026-124","summary":"","modified":"2026-05-20T09:19:15.840719Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<0.5.0b3.dev97"],"fixed":["0.5.0b3.dev97"]}]}],"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).
