Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-8088 is a path traversal vulnerability affecting the Windows version of WinRAR. It allows attackers to execute arbitrary code by crafting malicious archive files. This vulnerability was exploited in the wild. It was discovered by Anton Cherepanov, Peter Košinár, and Peter Strýček from ESET. The vulnerability was exploited in phishing attacks to deliver RomCom malware. The attackers can trick the program into saving a file in a different location than the user intended, such as the computer's Startup folder. This allows the attackers to execute their own code. WinRAR patched the vulnerability in version 7.13.
