{"id":"CVE-2026-35464","summary":"pyLoad has an incomplete fix for CVE-2026-33509: unprotected storage_folder enables arbitrary file write to Flask session store and code execution","details":"pyLoad is a free and open-source download manager written in Python. The fix for CVE-2026-33509 added an ADMIN_ONLY_OPTIONS set to block non-admin users from modifying security-critical config options. The storage_folder option is not in this set and passes the existing path restriction because the Flask session directory is outside both PKGDIR and userdir. A user with SETTINGS and ADD permissions can redirect downloads to the Flask filesystem session store, plant a malicious pickle payload as a predictable session file, and trigger arbitrary code execution when any HTTP request arrives with the corresponding session cookie. This vulnerability is fixed with commit c4cf995a2803bdbe388addfc2b0f323277efc0e1.","aliases":["GHSA-4744-96p5-mp2j","PYSEC-2026-2989"],"modified":"2026-07-15T01:48:52.050801101Z","published":"2026-04-07T14:38:02.480Z","related":["GHSA-4744-96p5-mp2j","GHSA-r7mc-x6x7-cqxx"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-502","CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35464.json","unresolved_ranges":[{"extracted_events":[{"last_affected":"0.5.0b3.dev96"}],"source":"AFFECTED_FIELD"}]},"references":[{"type":"WEB","url":"https://www.cve.org/CVERecord?id=CVE-2026-33509"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35464.json"},{"type":"ADVISORY","url":"https://github.com/pyload/pyload/security/advisories/GHSA-4744-96p5-mp2j"},{"type":"ADVISORY","url":"https://github.com/pyload/pyload/security/advisories/GHSA-r7mc-x6x7-cqxx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35464"},{"type":"FIX","url":"https://github.com/pyload/pyload/commit/c4cf995a2803bdbe388addfc2b0f323277efc0e1"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pyload/pyload","events":[{"introduced":"0"},{"fixed":"c4cf995a2803bdbe388addfc2b0f323277efc0e1"}],"database_specific":{"source":"REFERENCES"}}],"versions":["v0.4.9","v0.4.8","v0.4.7","v0.4.6","v0.4.5","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4","v0.3.2","v0.3.1","v0.3","v0.2.2","v0.2.1","v0.2","v0.1.1","v0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-35464.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
