CVE-2025-11002	Jan 23, 2026	7-Zip ZIP Symbolic Link RCE via Directory Traversal 7-Zip ZIP File Parsing Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of 7-Zip. Interaction with this product is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the handling of symbolic links in ZIP files. Crafted data in a ZIP file can cause the process to traverse to unintended directories. An attacker can leverage this vulnerability to execute code in the context of a service account. Was ZDI-CAN-26743.	7 Zip

This vulnerability allows remote attackers to execute arbitrary code on affected installations of 7-Zip. Interaction with this product is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the handling of symbolic links in ZIP files. Crafted data in a ZIP file can cause the process to traverse to unintended directories. An attacker can leverage this vulnerability to execute code in the context of a service account. Was ZDI-CAN-26753.	7 Zip
CVE-2025-55188	Aug 08, 2025	7-Zip <25.01: Symlink Extraction Vulnerability (LFI) 7-Zip before 25.01 does not always properly handle symbolic links during extraction.	7 Zip
CVE-2025-53817	Jul 17, 2025	7-Zip <25.0.0 DoS via NulPtr Deref in Compound Handler 7-Zip is a file archiver with a high compression ratio. 7-Zip supports extracting from Compound Documents. Prior to version 25.0.0, a null pointer dereference in the Compound handler may lead to denial of service. Version 25.0.0 contains a fix cor the issue.	7 Zip
CVE-2025-53816	Jul 17, 2025	7-Zip <25.0.0 RAR5 Handler Zero-Byte MemCorrupt & DoS 7-Zip is a file archiver with a high compression ratio. Zeroes written outside heap buffer in RAR5 handler may lead to memory corruption and denial of service in versions of 7-Zip prior to 25.0.0. Version 25.0.0 contains a fix for the issue.	7 Zip
CVE-2022-47111	Apr 19, 2025	7-Zip 22.01 DoS via Invalid xz Files (Block Flags/Reserved Bits) 7-Zip 22.01 does not report an error for certain invalid xz files, involving block flags and reserved bits. Some later versions are unaffected.	7 Zip
CVE-2022-47112	Apr 19, 2025	7-Zip 22.01 error-reporting flaw in XZ stream flag parsing 7-Zip 22.01 does not report an error for certain invalid xz files, involving stream flags and reserved bits. Some later versions are unaffected.	7 Zip
CVE-2025-0411	Jan 25, 2025	7-Zip MOTW Bypass Enables Remote Code Execution 7-Zip Mark-of-the-Web Bypass Vulnerability. This vulnerability allows remote attackers to bypass the Mark-of-the-Web protection mechanism on affected installations of 7-Zip. 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 archived files. When extracting files from a crafted archive that bears the Mark-of-the-Web, 7-Zip does not propagate the Mark-of-the-Web to the extracted files. An attacker can leverage this vulnerability to execute arbitrary code in the context of the current user. Was ZDI-CAN-25456.	7 Zip
CVE-2024-11477	Nov 22, 2024	7-Zip Zstd Decompression Integer Underflow RCE Vulnerability 7-Zip Zstandard Decompression Integer Underflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of 7-Zip. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the implementation of Zstandard decompression. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-24346.	7 Zip
CVE-2024-11612	Nov 22, 2024	7-Zip Infinite Loop DoS via CopyCoder 7-Zip CopyCoder Infinite Loop Denial-of-Service Vulnerability. This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of 7-Zip. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the processing of streams. The issue results from a logic error that can lead to an infinite loop. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-24307.	7 Zip
