{"cve":"CVE-2026-44340","nvd":{"published":"2026-05-08T14:16:47.040","modified":"2026-06-17T10:50:31.803","status":"Analyzed","description":"PraisonAI is a multi-agent teams system. Prior to version 4.6.37, the _safe_extractall helper that all recipe pull, recipe publish, and recipe unpack flows route through validates each archive member's name for absolute paths, .. segments, and resolved-path escape — but does not validate member.linkname, does not reject symlink/hardlink members, and calls tar.extractall(dest_dir) without filter=\"data\". A bundle that contains a symlink with a name inside dest_dir but a linkname pointing outside it, followed by a regular file whose path traverses through the just-created symlink, escapes dest_dir and lets the attacker write arbitrary content to an attacker-chosen location on the victim's filesystem. This issue has been patched in version 4.6.37.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-22","CWE-59"],"references":["https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-9q28-ghcr-c4x3"],"products":["praison:praisonai"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-44340","score":0.00433,"percentile":0.37619,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-9q28-ghcr-c4x3","url":"https://osv.dev/vulnerability/GHSA-9q28-ghcr-c4x3","summary":"PraisonAI's symlink-extraction bypass of `_safe_extractall` writes outside `dest_dir`","modified":"2026-07-13T16:42:29.244757472Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":["<4.6.37"],"fixed":["4.6.37"]}]},{"id":"PYSEC-2026-2909","url":"https://osv.dev/vulnerability/PYSEC-2026-2909","summary":"PraisonAI's symlink-extraction bypass of `_safe_extractall` writes outside `dest_dir`","modified":"2026-07-13T16:33:02.278378438Z","packages":[{"ecosystem":"PyPI","name":"praisonai","purl":"pkg:pypi/praisonai","ranges":["<4.6.37"],"fixed":["4.6.37"]}]}],"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).
