CVE-2026-25500 MEDIUM POC PATCH This Month

Rack's Directory module fails to sanitize filenames when generating HTML directory listings, allowing attackers to craft files with javascript: scheme names that execute arbitrary code when clicked. Authenticated users or those with access to directories containing maliciously named files can trigger stored XSS attacks affecting other users viewing the directory index. Public exploit code exists for versions prior to 2.2.22, 3.1.20, and 3.2.5.

CVE-2026-22860 HIGH POC PATCH This Week

Directory traversal in Rack versions prior to 2.2.22, 3.1.20, and 3.2.5 allows unauthenticated remote attackers to list directories outside the configured root by exploiting a string prefix matching flaw in path validation. An attacker can craft requests with path traversal sequences to enumerate sensitive directories if the target path shares a common prefix with the configured root directory. Public exploit code exists for this vulnerability.

CVE-2025-49007 MEDIUM PATCH This Month

Rack is a modular Ruby web server interface. Starting in version 3.1.0 and prior to version 3.1.16, there is a denial of service vulnerability in the Content-Disposition parsing component of Rack. This is very similar to the previous security issue CVE-2022-44571. Carefully crafted input can cause Content-Disposition header parsing in Rack to take an unexpected amount of time, possibly resulting in a denial of service attack vector. This header is used typically used in multipart parsing. Any applications that parse multipart posts using Rack (virtually all Rails applications) are impacted. Version 3.1.16 contains a patch for the vulnerability.
