A critical security vulnerability has been identified and patched in the widely used file archiving software, WinRAR. This flaw, tracked as CVE-2025-6218, poses a significant risk to users, potentially allowing attackers to execute arbitrary code on affected systems.
The vulnerability is classified as a Remote Code Execution (RCE) flaw. It specifically impacts WinRAR versions prior to 6.24. The issue arises when WinRAR attempts to process specially crafted recovery volumes (.rev files) within a malicious .RAR archive. An attacker could exploit this by convincing a user to open such a malicious archive. If successful, they could potentially take control of the user’s computer without further interaction.
This serious vulnerability was discovered by security researchers at Check Point Software, highlighting the ongoing need for vigilance in software security.
Thankfully, a fix has been released. The vulnerability is resolved in WinRAR version 6.24 and later.
Given the severity of this RCE vulnerability and the potential for widespread impact due to WinRAR’s popularity, it is imperative that all users take immediate action. Delaying the update leaves systems exposed to potential attack.
To protect yourself and your data, you must update WinRAR immediately to the latest available version (6.24 or newer). This is a critical security update that should not be ignored. Check for updates within the WinRAR application or download the latest version directly from the official WinRAR website.
Do not delay. Update your WinRAR software now to patch this critical RCE vulnerability and ensure your system remains secure.
