Versions 9.2.1 and below contain a Path Traversal vulnerability that allows arbitrary file writes anywhere the user has write permissions. On Windows, this leads to Remote Code Execution by writing a payload to the Startup folder, which executes on next login. Function extract_pictures only checks startswith('Pictures'), and does not sanitize '..' sequences. calibre's own ZipFile.extractall() in utils/zipfile.py does sanitize '..' via _get_targetpath(), but extract_pictures() bypasses this by using manual zf.read() + open(). This issue has been fixed in version 9.3.0.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2026-26064","url":"https://www.suse.com/security/cve/CVE-2026-26064"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1258529 for CVE-2026-26064","url":"https://bugzilla.suse.com/1258529"}],"title":"SUSE CVE CVE-2026-26064","tracking":{"current_release_date":"2026-02-22T00:24:37Z","generator":{"date":"2026-02-21T00:24:09Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2026-26064","initial_release_date":"2026-02-21T00:24:09Z","revision_history":[{"date":"2026-02-21T00:24:09Z","number":"2","summary":"references added,severity changed from  to moderate"},{"date":"2026-02-22T00:24:37Z","number":"3","summary":"severity changed from moderate to important"}],"status":"interim","version":"3"}}}
