XSS in Generate Report of WinRAR 7.11 (User Interaction Required)
CVE-2025-52331 6.1 - Medium - November 12, 2025

Cross-site scripting (XSS) vulnerability in the generate report functionality in Rarlab WinRAR 7.11, allows attackers to disclose user information such as the computer username, generated report directory, and IP address. The generate report command includes archived file names without validation in the HTML report, which allows potentially malicious HTML tags to be injected into the report. User interaction is required. User must use the "generate report" functionality and open the report.

RCE via Path Traversal in WinRAR Windows
CVE-2025-8088 - August 08, 2025

A path traversal vulnerability affecting the Windows version of WinRAR allows the attackers to execute arbitrary code by crafting malicious archive files. This vulnerability was exploited in the wild and was discovered by Anton Cherepanov, Peter Koinár, and Peter Strýek from ESET.

Path Traversal: '.../...//'

WinRAR RCE via Zip Filename Spoofing
CVE-2014-125119 - July 25, 2025

A filename spoofing vulnerability exists in WinRAR when opening specially crafted ZIP archives. The issue arises due to inconsistencies between the Central Directory and Local File Header entries in ZIP files. When viewed in WinRAR, the file name from the Central Directory is displayed to the user, while the file from the Local File Header is extracted and executed. An attacker can leverage this flaw to spoof filenames and trick users into executing malicious payloads under the guise of harmless files, potentially leading to remote code execution.

WinRAR Directory Traversal RCE via Crafted Archive Path
CVE-2025-6218 - June 21, 2025

RARLAB WinRAR Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of RARLAB WinRAR. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of file paths within archive files. A crafted file path can cause the process to traverse to unintended directories. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-27198.

WinRAR <7.11: Bypass MOW via Symlink for Exec Code
CVE-2025-31334 - April 03, 2025

Issue that bypasses the "Mark of the Web" security warning function for files when opening a symbolic link that points to an executable file exists in WinRAR versions prior to 7.11. If a symbolic link specially crafted by an attacker is opened on the affected product, arbitrary code may be executed.

WinRAR before 7.00 Screen Spoofing via ANSI Escape Sequences
CVE-2024-36052 - May 21, 2024

RARLAB WinRAR before 7.00, on Windows, allows attackers to spoof the screen output via ANSI escape sequences, a different issue than CVE-2024-33899.

RARLAB WinRAR RC Array Index RCE via Recovery Volume
CVE-2023-40477 - May 03, 2024

RARLAB WinRAR Recovery Volume Improper Validation of Array Index Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of RARLAB WinRAR. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the processing of recovery volumes. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-21233.

WinRAR <7.00: Screen Spoof/DoS via ANSI Escape Sequences
CVE-2024-33899 - April 29, 2024

RARLAB WinRAR before 7.00, on Linux and UNIX platforms, allows attackers to spoof the screen output, or cause a denial of service, via ANSI escape sequences.

WinRAR Mark-Of-The-Web Bypass via Archive Extraction
CVE-2024-30370 - April 02, 2024

RARLAB WinRAR Mark-Of-The-Web Bypass Vulnerability. This vulnerability allows remote attackers to bypass the Mark-Of-The-Web protection mechanism on affected installations of RARLAB WinRAR. User interaction is required to exploit this vulnerability in that the target must perform a specific action on a malicious page. The specific flaw exists within the archive extraction functionality. A crafted archive entry can cause the creation of an arbitrary file without the Mark-Of-The-Web. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current user. Was ZDI-CAN-23156.

WinRAR <6.23 RCE via ZIP Filename Collision
CVE-2023-38831 7.8 - High - August 23, 2023

RARLAB WinRAR before 6.23 allows attackers to execute arbitrary code when a user attempts to view a benign file within a ZIP archive. The issue occurs because a ZIP archive may include a benign file (such as an ordinary .JPG file) and also a folder that has the same name as the benign file, and the contents of the folder (which may include executable content) are processed during an attempt to access only the benign file. This was exploited in the wild in April through October 2023.

Insufficient Type Distinction

RARLAB WinRAR 6.11.0.0 ZIP Buffer Overread
CVE-2022-43650 7.1 - High - March 29, 2023

This vulnerability allows remote attackers to disclose sensitive information on affected installations of RARLAB WinRAR 6.11.0.0. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of ZIP files. Crafted data in a ZIP file can trigger a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-19232.

Out-of-bounds Read

In WinRAR versions prior to and including 5.60
CVE-2018-20253 - February 13, 2019

In WinRAR versions prior to and including 5.60, There is an out-of-bounds write vulnerability during parsing of a crafted LHA / LZH archive formats. Successful exploitation could lead to arbitrary code execution in the context of the current user.

Memory Corruption

In WinRAR versions prior to and including 5.61
CVE-2018-20250 7.8 - High - February 05, 2019

In WinRAR versions prior to and including 5.61, There is path traversal vulnerability when crafting the filename field of the ACE format (in UNACEV2.dll). When the filename field is manipulated with specific patterns, the destination (extraction) folder is ignored, thus treating the filename as an absolute path.

Absolute Path Traversal

In WinRAR versions prior to and including 5.61, there is path traversal vulnerability when crafting the filename field of the ACE format
CVE-2018-20251 - February 05, 2019

In WinRAR versions prior to and including 5.61, there is path traversal vulnerability when crafting the filename field of the ACE format. The UNACE module (UNACEV2.dll) creates files and folders as written in the filename field even when WinRAR validator noticed the traversal attempt and requestd to abort the extraction process. the operation is cancelled only after the folders and files were created but prior to them being written, therefore allowing the attacker to create empty files and folders everywhere in the file system.

Protection Mechanism Failure

In WinRAR versions prior to and including 5.60
CVE-2018-20252 - February 05, 2019

In WinRAR versions prior to and including 5.60, there is an out-of-bounds write vulnerability during parsing of crafted ACE and RAR archive formats. Successful exploitation could lead to arbitrary code execution in the context of the current user.
