- CVE-2023-40481:
(needs triaging)
7-Zip SquashFS File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code 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 parsing of SQFS files. The issue results from the lack of proper validation of user-supplied data, which can result in a write 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-18589.
- CVE-2025-11001:
(needs triaging)
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-26753.
- CVE-2025-11002:
(needs triaging)
- CVE-2025-55188:
