CVE Severity Published▾ Status Exploitation Description
CVE-2026-97370 High 2026-10-15 No exploit published No public exploit Junrar is an open source Java RAR archive library. Prior to 7.6.1, RarVM.ExecuteCode in src/main/java/com/github/junrar/unpack/vm/RarVM.java can repeatedly execute a VM_JMP instruction whose target is greater than or equal to the prepared program's codeSize. The setIP() function returns success without changing the instruction pointer or decrementing maxOpCount, and the jump handler continues before loop-end accounting, leaving both values unchanged. A crafted RAR4 archive can therefore keep an extraction thread in an infinite CPU loop and exhaust archive-processing worker capacity. The RAR virtual machine does not expose native process execution, so the supported impact is availability loss rather than code execution. This issue is fixed in version 7.6.1.
CVE-2026-86071 Low 2026-09-16 Protected by Waratek No public exploit Junrar is an open source Java RAR archive library. Prior to version 7.6.1, LocalFolderExtractor in src/main/java/com/github/junrar/LocalFolderExtractor.java can create directories outside the intended extraction root when processing a crafted archive entry. LocalFolderExtractor.createFile() validates only the final canonical file path, while LocalFolderExtractor.makeFile() creates intermediate path segments with unchecked mkdir() calls. An entry can therefore make the final path resolve inside the destination while causing intermediate directory creation outside it, enabling filesystem pollution or file-versus-directory squatting that can make later security-sensitive writes fail. The demonstrated impact is directory creation, not unconditional arbitrary file-content write. This issue is fixed in version 7.6.1.
CVE-2026-41245 Critical 2026-04-20 Protected by Waratek No public exploit Junrar is an open source java RAR archive library. Prior to version 7.5.10, a path traversal vulnerability in `LocalFolderExtractor` allows an attacker to write arbitrary files with attacker-controlled content into sibling directories when a crafted RAR archive is extracted. Version 7.5.10 fixes the issue.
CVE-2026-28208 Medium 2026-02-26 Protected by Waratek Proof of concept only 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.
CVE-2022-23596 High 2022-02-01 No exploit published Proof of concept only Junrar is an open source java RAR archive library. In affected versions A carefully crafted RAR archive can trigger an infinite loop while extracting said archive. The impact depends solely on how the application uses the library, and whether files can be provided by malignant users. The problem is patched in 7.4.1. There are no known workarounds and users are advised to upgrade as soon as possible.
CVE-2018-12418 Medium 2018-06-14 No exploit published No public exploit Archive.java in Junrar before 1.0.1, as used in Apache Tika and other products, is affected by a denial of service vulnerability due to an infinite loop when handling corrupt RAR files.
