Technical details

A directory traversal vulnerability (CWE-22) exists in RARLAB WinRAR due to improper handling of file paths within archive files. By crafting an archive with malicious path sequences, an attacker can cause the application to write files to unintended directories during extraction. Exploitation requires user interaction, such as opening a malicious archive file. Successful exploitation allows for remote code execution in the security context of the current user. This vulnerability is tracked as CVE-2025-6218 and has been added to CISA's Known Exploited Vulnerabilities (KEV) catalog. The issue is addressed in WinRAR version 7.12.
