Vulnerability from github – Published: 2026-09-29 18:32 – Updated: 2026-09-29 18:32

Details

Marmite through 0.4.2 contains a path traversal vulnerability in the development server started by --serve that allows unauthenticated attackers to read arbitrary files. The handle_request function in src/server.rs fails to reject .. segments after percent-decoding and joining the request path to the output folder, enabling attackers to request encoded traversal sequences to access files readable by the marmite process.

Severity

7.5 (High)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
