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.
With a CVSS score of 7.8, this vulnerability is classified as high severity. Organizations using 7-zip should be aware that risk to organizations includes the potential for unauthorized code execution, which can lead to significant data compromise or service disruptions. Due to the nature of the vulnerability, it presents a real-world risk that could be exploited if not addressed promptly.
As of now, there is a known exploit for this vulnerability, and organizations should prioritize patching immediately to mitigate risks associated with this vulnerability. Regular updates and security assessments are crucial to maintaining the integrity of systems utilizing 7-zip.
This vulnerability was published on January 23, 2026, and has been actively analyzed for its impact and exploitability. Organizations must remain vigilant and ensure that their installations are updated with the latest security patches.
Vulnerability Details
The 7-Zip ZIP File Parsing Directory Traversal Remote Code Execution Vulnerability is identified as CWE-22. The specific flaw allows crafted ZIP files to exploit symbolic links, leading to directory traversal. This can result in arbitrary code execution, making it critical for users to apply the necessary updates to their installations.
The vulnerability affects 7-Zip version 24.09 and potentially earlier versions. Organizations should verify their software versions and patch accordingly.
Technical Analysis
The root cause of this vulnerability stems from improper handling of symbolic links in ZIP files. The attack vector is classified as local, meaning that an attacker needs to have access to the ZIP file in question. The attack complexity is low, as user interaction is required to open the ZIP file, but once opened, the exploit can be executed.
This vulnerability requires no privileges to exploit, but it does necessitate user interaction, as the victim must open the affected ZIP file. The impacts of this vulnerability include high confidentiality, integrity, and availability risks, as attackers may execute arbitrary code and potentially gain access to sensitive information or disrupt services.
Risk & Impact Analysis
Organizations utilizing 7-zip should assess their risk exposure concerning this vulnerability due to its potential for exploitation. The blast radius includes any systems where 7-zip is installed and utilized, particularly in environments where ZIP files are frequently exchanged or downloaded from untrusted sources.
The urgency for organizations to address this vulnerability is high, given the ease of exploitation and the significant impact it can have on data security and operational continuity. Organizations should prioritize remediation efforts based on their risk assessment and operational needs.
