https://notcve.org/view.php?id=CVE-2025-27610
10 Mar 2025 — 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 th... • https://github.com/rack/rack/commit/50caab74fa01ee8f5dbdee7bb2782126d20c6583 • CWE-23: Relative Path Traversal •

https://notcve.org/view.php?id=CVE-2025-27111
04 Mar 2025 — Rack is a modular Ruby web server interface. The Rack::Sendfile middleware logs unsanitised header values from the X-Sendfile-Type header. An attacker can exploit this by injecting escape sequences (such as newline characters) into the header, resulting in log injection. This vulnerability is fixed in 2.2.12, 3.0.13, and 3.1.11. Nhật Thái Đỗ discovered that Rack incorrectly handled certain usernames. • https://github.com/rack/rack/commit/803aa221e8302719715e224f4476e438f2531a53 • CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection') CWE-117: Improper Output Neutralization for Logs •

12 Feb 2025 — Rack provides an interface for developing web applications in Ruby. Prior to versions 2.2.11, 3.0.12, and 3.1.11, Rack::CommonLogger can be exploited by crafting input that includes newline characters to manipulate log entries. The supplied proof-of-concept demonstrates injecting malicious content into logs. When a user provides the authorization credentials via Rack::Auth::Basic, if success, the username will be put in env['REMOTE_USER'] and later be used by Rack::CommonLogger for logging purposes.

https://notcve.org/view.php?id=CVE-2024-26141
28 Feb 2024 — Rack is a modular Ruby web server interface. Carefully crafted Range headers can cause a server to respond with an unexpectedly large response. Responding with such large responses could lead to a denial of service issue. Vulnerable applications will use the `Rack::File` middleware or the `Rack::Utils.byte_ranges` methods (this includes Rails applications). The vulnerability is fixed in 3.0.9.1 and 2.2.8.1. • https://discuss.rubyonrails.org/t/possible-dos-vulnerability-with-range-header-in-rack/84944 • CWE-400: Uncontrolled Resource Consumption CWE-1333: Inefficient Regular Expression Complexity •

28 Feb 2024 — Rack is a modular Ruby web server interface. Carefully crafted headers can cause header parsing in Rack to take longer than expected resulting in a possible denial of service issue. Accept and Forwarded headers are impacted. Ruby 3.2 has mitigations for this problem, so Rack applications using Ruby 3.2 or newer are unaffected.
