CVE-2025-27610 is a path traversal vulnerability found in Rack, a Ruby web server interface, specifically within the Rack::Static middleware. This vulnerability arises because Rack::Static doesn't properly sanitize user-supplied paths when serving files. This lack of sanitization allows attackers to use encoded path traversal sequences to access files outside the intended static file directory. By exploiting this vulnerability, an attacker could potentially gain unauthorized access to sensitive information, including configuration files, credentials, and other confidential data located within the specified "root" directory. To successfully exploit this, the attacker needs to be able to determine the path of the files they are trying to access.

Description
Rack provides an interface for developing web applications in Ruby. Prior to versions 2.2.13, 3.0.14, and 3.1.12, `Rack::Static` can serve files under the specified `root:` even if `urls:` are provided, which may expose other files under the specified `root:` unexpectedly. The vulnerability occurs because `Rack::Static` does not properly sanitize user-supplied paths before serving files. Specifically, encoded path traversal sequences are not correctly validated, allowing attackers to access files outside the designated static file directory. By exploiting this vulnerability, an attacker can gain access to all files under the specified `root:` directory, provided they are able to determine then path of the file. Versions 2.2.13, 3.0.14, and 3.1.12 contain a patch for the issue. Other mitigations include removing usage of `Rack::Static`, or ensuring that `root:` points at a directory path which only contains files which should be accessed publicly. It is likely that a CDN or similar static file server would also mitigate the issue.
