CVE-2024-47067: 
NixOS vulnerability analysis and mitigation

CVE-2024-47067 is a reflected cross-site scripting (XSS) vulnerability discovered in AList, a file list program that supports multiple storages. The vulnerability was identified in the helper.go file, specifically in the endpoint /i/:linkname which processes user-provided values and reflects them back in the response. The vulnerability was discovered in version 3.28.0 and has been fixed in version 3.29.0 ([GitHub Advisory](https://securitylab.github.com/advisories/GHSL-2023-220Alist/), NVD).

The vulnerability exists due to improper handling of user input in the /i/:link_name endpoint. When the endpoint returns an application/xml response, it becomes susceptible to HTML tags via XHTML, leading to cross-site scripting. The vulnerability has been assigned a CVSS v4.0 base score of 5.1 (Medium) and a CVSS v3.1 base score of 6.1 (Medium), with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N (NVD).

The exploitation of this vulnerability could allow an unauthenticated attacker to steal JWT tokens from users who click on specially crafted links. In the worst-case scenario, this could lead to unauthorized access to copy, delete, and read arbitrary files on connected services or locally (GitHub Advisory).

The vulnerability has been patched in AList version 3.29.0. Users are advised to upgrade to this version or later to mitigate the risk. The fix involves properly sanitizing user input in the helper.go file (GitHub Patch).
