By using the document event feature to trigger LibreLogo to execute python contained within a document a malicious document could be constructed which would execute arbitrary python commands silently without warning. In the fixed versions, LibreLogo cannot be called from a document event handler. This issue affects: Document Foundation LibreOffice versions prior to 6.2.5.","published":"2019-07-17T12:15:11.000Z","lastModified":"2026-06-17T02:44:43.000Z","status":"Modified","sourceIdentifier":"security@documentfoundation.org","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-94"],"affected":["libreoffice/libreoffice","canonical/ubuntu linux","fedoraproject/fedora","debian/debian linux","opensuse/leap"],"epss":{"score":0.2887,"percentile":0.98156,"date":"2026-11-03","history":[{"date":"2026-09-28","score":0.2887,"percentile":0.98096}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 28.9%, higher than 98% of all known CVEs.
