NuGet Gallery is a package repository that powers nuget.org. The NuGetGallery has a security vulnerability related to its handling of autolinks in Markdown content. While the platform properly filters out JavaScript from standard links, it does not adequately sanitize autolinks. This oversight allows attackers to exploit autolinks as a vector for Cross-Site Scripting (XSS) attacks. This vulnerability is fixed in 2024.12.06.

A tampering vulnerability exists in NuGet software when executed in a Linux or Mac environment. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user.

A tampering vulnerability exists in the NuGet Package Manager for Linux and Mac that could allow an authenticated attacker to modify contents of the intermediate build folder (by default "obj"), aka 'NuGet Package Manager Tampering Vulnerability'.

An authenticated user without repository read permission may access private NuGet metadata under specific conditions.
