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.","provenance":"source","from":"CVE.org"},"cvss":{"score":5.9,"severity":"MEDIUM","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","provenance":"source","from":"CVE.org CNA"},"epss":{"score":0.14739,"percentile":0.96663,"provenance":"source"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"references":[{"url":"https://github.com/junrar/junrar/security/advisories/GHSA-j273-m5qq-6825","tags":["x_refsource_CONFIRM"]},{"url":"https://github.com/junrar/junrar/commit/947ff1d33f00f940aa68ae2593500291d799d954","tags":["x_refsource_MISC"]},{"url":"https://github.com/junrar/junrar/releases/tag/v7.5.8","tags":["x_refsource_MISC"]}],"priority":{"score":23.5,"factors":[{"name":"EPSS percentile","points":19.33},{"name":"CVSS severity","points":4.13}]},"vendorSlug":"junrar","affectedVersions":[{"vendor":"junrar","product":"junrar","versions":["< 7.5.8"]}],"affected":[{"ecosystem":"Maven","package":"com.github.junrar:junrar","vulnerableRanges":["<7.5.8"],"patched":["7.5.8"],"from":["GHSA-j273-m5qq-6825"],"provenance":"source"}],"euvd":{"id":"EUVD-2026-8909","exploited":false,"provenance":"source"},"lineage":{"familyId":"fam-junrar-cve-2026-28208","packageHistory":[{"cve":"CVE-2018-12418","published":"2018-06-14","fixed":"1.0.1","kev":false},{"cve":"CVE-2022-23596","published":"2022-02-01","fixed":"7.4.1","kev":false},{"cve":"CVE-2026-28208","published":"2026-02-26","fixed":"7.5.8","kev":false},{"cve":"CVE-2026-41245","published":"2026-04-20","fixed":"7.5.10","kev":false,"link":{"from":"CVE-2026-28208","to":"CVE-2026-41245","relation":"successor","confidence":"medium","kind":"sequence","evidence":[{"kind":"version-step","provenance":"source","package":"Maven:com.github.junrar:junrar","fromFixed":"7.5.8","toFixed":"7.5.10","daysApart":53},{"kind":"similar","provenance":"machine","score":0.73,"basis":"same product + CWE + description similarity"}]}},{"cve":"CVE-2026-86071","published":"2026-09-16","fixed":"7.6.1","kev":false},{"cve":"CVE-2026-97370","published":"2026-10-15","fixed":"7.6.1","kev":false}],"package":"Maven:com.github.junrar:junrar"}}
