Litestar and Starlite is an Asynchronous Server Gateway Interface (ASGI) framework. Prior to 2.8.3, 2.7.2, and 2.6.4, a Local File Inclusion (LFI) vulnerability has been discovered in the static file serving component of LiteStar. This vulnerability allows attackers to exploit path traversal flaws, enabling unauthorized access to sensitive files outside the designated directories. Such access can lead to the disclosure of sensitive information or potentially compromise the server. The vulnerability is located in the file path handling mechanism within the static content serving function, specifically at `litestar/static_files/base.py`. This vulnerability is fixed in versions 2.8.3, 2.7.2, and 2.6.4.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
