CyberRota Analysis
AI-GeneratedMailpit versions prior to 1.30.0 are vulnerable to a path traversal attack via the `mailpit dump --http` sub-command, allowing an attacker to manipulate the output path and write files to arbitrary locations on the user's system. This could lead to unauthorized file creation or overwriting, potentially compromising sensitive data or system integrity. Developers and organizations using Mailpit for email testing should prioritize upgrading to version 1.30.0 to mitigate this risk.

Original NVD Description
Mailpit is an email testing tool and API for developers. Prior to version 1.30.0, the mailpit dump --http <base-url> <out-dir> sub-command downloads every message from a remote Mailpit instance and writes each one as <id>.eml inside the user-supplied output directory. The message ID field is taken verbatim from the JSON response of the remote server and concatenated into the output path with path.Join, which silently normalizes `..` segments. A malicious HTTP server impersonating Mailpit can therefore make mailpit dump write attacker-controlled bytes to any path the running user can write, fully outside the intended output directory. Version 1.30.0 contains a patch.
