In 2.6 and earlier, attribute_filter is not consistently applied when attributes are accessed through built-in functions like getattr and setattr. This allows an attacker to bypass the intended restrictions and eventually achieve arbitrary code execution.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H","score":7.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","score":10.0},"cwes":["CWE-284","CWE-639","CWE-914"],"references":["https://github.com/scoder/lupa/security/advisories/GHSA-69v7-xpr6-6gjm","https://access.redhat.com/errata/RHSA-2026:22993","https://access.redhat.com/security/cve/CVE-2026-34444","https://bugzilla.redhat.com/show_bug.cgi?id=2455413","https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-34444.json"],"products":["scoder:lupa"],"source":"nvd","synced_at":"2026-10-26T21:38:48.864438205+00:00"},"epss":{"cve":"CVE-2026-34444","score":0.00613,"percentile":0.49062,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-69v7-xpr6-6gjm","url":"https://osv.dev/vulnerability/GHSA-69v7-xpr6-6gjm","summary":"Lupa has a Sandbox escape and RCE due to incomplete attribute_filter enforcement in getattr / setattr","modified":"2026-09-10T03:50:43.384103709Z","packages":[{"ecosystem":"PyPI","name":"lupa","purl":"pkg:pypi/lupa","ranges":["<=2.6"],"fixed":[]}]},{"id":"PYSEC-2026-2613","url":"https://osv.dev/vulnerability/PYSEC-2026-2613","summary":"Lupa has a Sandbox escape and RCE due to incomplete attribute_filter enforcement in getattr / setattr","modified":"2026-07-13T16:32:12.344758112Z","packages":[{"ecosystem":"PyPI","name":"lupa","purl":"pkg:pypi/lupa","ranges":["<=2.6"],"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).
