CVE-2026-96884 Details
Description
A security flaw has been discovered in MantisZip up to 0.4.5. Affected by this issue is the function Path.Combine of the file MainWindow.UI.cs of the component Preview. The manipulation results in path traversal. It is possible to launch the attack remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
A path traversal vulnerability has been identified in MantisZip versions through 0.4.5. This issue arises in the Preview component, specifically within the Path.Combine function of MainWindow.UI.cs. The vulnerability allows for arbitrary file writing by exploiting the application's handling of ZIP entry names, which are not properly sanitized before being used to construct file paths. As a result, an attacker can craft a malicious ZIP file that escapes the designated temporary directory and writes files to any user-writable location on the system. The vulnerability can be exploited remotely, with the released public exploit available for use.
To address this vulnerability, MantisZip should implement proper input sanitization by using functions that discard path information from ZIP entry names, retaining only the file name. Additionally, the application should validate that resolved file paths remain within the intended temporary directory before performing any file operations.
