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 •
CVSS: 9.8EPSS: 0%CPEs: 3EXPL: 0CVE-2025-27111 – Escape Sequence Injection vulnerability in Rack lead to Possible Log Injection
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 •

https://notcve.org/view.php?id=CVE-2025-25184
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. The iss... • https://github.com/rack/rack/commit/074ae244430cda05c27ca91cda699709cfb3ad8e • CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection') CWE-117: Improper Output Neutralization for Logs •
CVSS: 6.8EPSS: 0%CPEs: 1EXPL: 0CVE-2024-39316 – Rack ReDoS Vulnerability in HTTP Accept Headers Parsing
https://notcve.org/view.php?id=CVE-2024-39316
02 Jul 2024 — Rack is a modular Ruby web server interface. Starting in version 3.1.0 and prior to version 3.1.5, Regular Expression Denial of Service (ReDoS) vulnerability exists in the `Rack::Request::Helpers` module when parsing HTTP Accept headers. This vulnerability can be exploited by an attacker sending specially crafted `Accept-Encoding` or `Accept-Language` headers, causing the server to spend excessive time processing the request and leading to a Denial of Service (DoS). The fix for CVE-2024-26146 was not applie... • https://github.com/rack/rack/commit/412c980450ca729ee37f90a2661f166a9665e058 • CWE-1333: Inefficient Regular Expression Complexity •
