{"id":"CVE-2026-28208","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-28208","generatedAt":"2026-10-28T03:29:24.246Z","title":"Prior to version 7.5.8, a backslash path traversal vulnerability in `LocalFolderExtractor` allows an attacker to write arbitrary files with attacker-controlled content anywhere on the filesystem when a crafted RAR archive is extracted on Linux/Unix.","description":"Junrar is an open source java RAR archive library. Prior to version 7.5.8, a backslash path traversal vulnerability in `LocalFolderExtractor` allows an attacker to write arbitrary files with attacker-controlled content anywhere on the filesystem when a crafted RAR archive is extracted on Linux/Unix. This can often lead to remote code execution (e.g., overwriting shell profiles, source code, cron jobs, etc). Version 7.5.8 has a fix for the issue.","published":"2026-02-26T23:16:35.000Z","lastModified":"2026-06-17T10:28:20.000Z","status":"Modified","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N"},"cwe":["CWE-22"],"affected":["junrar project/junrar"],"epss":{"score":0.14739,"percentile":0.96652,"date":"2026-10-26","history":[{"date":"2026-09-24","score":0.00726,"percentile":0.52076},{"date":"2026-10-25","score":0.14739,"percentile":0.96651}]},"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 14.7%, higher than 97% of all known CVEs.
