The use of Python's marshal module to handle unchecked input in a public method on `PortalFolder` objects can lead to an unauthenticated denial of service and crash situation. The code in question is exposed by all portal software built on top of `Products.CMFCore`, such as Plone. All deployments are vulnerable. The code has been fixed in `Products.CMFCore` version 3.2.","aliases":["GHSA-4hpj-8rhv-9x87","PYSEC-2023-113"],"modified":"2026-04-26T04:17:18.507680Z","published":"2023-07-03T16:48:36.149Z","database_specific":{"cwe_ids":["CWE-770"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/36xxx/CVE-2023-36814.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/36xxx/CVE-2023-36814.json"},{"type":"ADVISORY","url":"https://github.com/zopefoundation/Products.CMFCore/security/advisories/GHSA-4hpj-8rhv-9x87"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-36814"},{"type":"FIX","url":"https://github.com/zopefoundation/Products.CMFCore/commit/40f03f43a60f28ca9485c8ef429efef729be54e5"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/zopefoundation/Products.CMFCore","events":[{"introduced":"0"},{"fixed":"4ac51b398fe542f6f979ed87f7dbd73784746bf1"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.2"}],"source":"CPE_FIELD","cpe":"cpe:2.3:a:zope:products.cmfcore:*:*:*:*:*:*:*:*"}}],"versions":["2.4.0","2.4.0b1","2.4.0b3","2.4.0b4","2.4.0b5","2.4.0b6","2.4.0b7","2.4.0b8","2.4.2","2.4.3","2.4.4","2.4.5","2.4.6","2.4.7","2.4.8","2.5.0","2.5.1","2.5.2","2.5.3","2.5.4","2.6.0","2.7.0","3.0","3.1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-36814.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/zopefoundation/products.cmfcore","events":[{"introduced":"0"},{"fixed":"40f03f43a60f28ca9485c8ef429efef729be54e5"}],"database_specific":{"source":"REFERENCES"}}],"versions":["2.4.0","2.4.0b1","2.4.0b3","2.4.0b4","2.4.0b5","2.4.0b6","2.4.0b7","2.4.0b8","2.4.2","2.4.3","2.4.4","2.4.5","2.4.6","2.4.7","2.4.8","2.5.0","2.5.1","2.5.2","2.5.3","2.5.4","2.6.0","2.7.0","3.0","3.1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-36814.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
