CISA KEV Advisory
RARLAB WinRAR Path Traversal Vulnerability
RARLAB WinRAR contains a path traversal vulnerability allowing an attacker to execute code in the context of the current user.
Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
Risk Analysis
RARLAB WinRAR contains a path traversal vulnerability that allows an attacker to execute code in the context of the current user. With a CVSS score of 7.8 and a high EPSS score of 0.05469, this vulnerability poses a significant risk, further emphasized by its inclusion in CISA's KEV, confirming active exploitation.
This vulnerability is actively being exploited in the wild. Exploitation requires user interaction, as it allows code execution in the context of the current user.
Users should update RARLAB WinRAR to the latest secure version immediately. Exercise caution when opening compressed files from untrusted sources.
Technical Analysis
CVE-2025-6218 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
CISA has added CVE-2025-6218 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
