{"id":"CVE-2019-9852","url":"https://www.cyber-defence.io/tools/cve/CVE-2019-9852","generatedAt":"2026-10-27T21:17:32.006Z","title":"LibreOffice has a feature where documents can specify that pre-installed macros can be executed on various script events such as mouse-over, document-open etc.","description":"LibreOffice has a feature where documents can specify that pre-installed macros can be executed on various script events such as mouse-over, document-open etc. Access is intended to be restricted to scripts under the share/Scripts/python, user/Scripts/python sub-directories of the LibreOffice install. Protection was added, to address CVE-2018-16858, to avoid a directory traversal attack where scripts in arbitrary locations on the file system could be executed. However this new protection could be bypassed by a URL encoding attack. In the fixed versions, the parsed url describing the script location is correctly encoded before further processing. This issue affects: Document Foundation LibreOffice versions prior to 6.2.6.","published":"2019-08-15T22:15:22.000Z","lastModified":"2026-06-17T02:44:43.000Z","status":"Modified","sourceIdentifier":"security@documentfoundation.org","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"cwe":["CWE-116","CWE-22"],"affected":["canonical/ubuntu linux","debian/debian linux","fedoraproject/fedora","opensuse/leap","libreoffice/libreoffice"],"epss":{"score":0.01752,"percentile":0.77735,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (1.75%).
