The stored passwords are encrypted with a single master key provided by the user. A flaw in LibreOffice existed where master key was poorly encoded resulting in weakening its entropy from 128 to 43 bits making the stored passwords vulerable to a brute force attack if an attacker has access to the users stored config. This issue affects: The Document Foundation LibreOffice 7.2 versions prior to 7.2.7; 7.3 versions prior to 7.3.3.","published_at":"2022-07-25T00:00:00Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-326"],"nvd_references":["https://www.libreoffice.org/about-us/security/advisories/cve-2022-26307","http://www.openwall.com/lists/oss-security/2022/08/13/2","https://lists.debian.org/debian-lts-announce/2023/03/msg00022.html"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:17:17.655521Z"},"effective_severity":null,"badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"the-document-foundation","vendor_name":"The Document Foundation","product_slug":"libreoffice","product_name":"LibreOffice","version_start":"7.2","version_start_inclusive":true,"version_end":"7.2.7","version_end_inclusive":false,"cpe23_uri":"cve5:the-document-foundation:libreoffice:7.2:7.2.7"},{"vendor_slug":"the-document-foundation","vendor_name":"The Document Foundation","product_slug":"libreoffice","product_name":"LibreOffice","version_start":"7.3","version_start_inclusive":true,"version_end":"7.3.3","version_end_inclusive":false,"cpe23_uri":"cve5:the-document-foundation:libreoffice:7.3:7.3.3"}],"exploit_refs":[],"news":[],"references":[{"url":"https://www.libreoffice.org/about-us/security/advisories/cve-2022-26307","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"http://www.openwall.com/lists/oss-security/2022/08/13/2","source_type":"MAILING_LIST","tags":["mailing-list"]},{"url":"https://lists.debian.org/debian-lts-announce/2023/03/msg00022.html","source_type":"MAILING_LIST","tags":["mailing-list"]}],"timeline":[{"type":"published","at":"2022-07-25T00:00:00Z","label":"CVE published","source":null}]}
