| 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-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. |
