Rack::Static prefix matching can expose unintended files under the static root

Summary Rack::Static determines whether a request should be served as a static file using a simple string prefix check. When configured with URL prefixes such as "/css", it matches any request path that begins with that string, including unrelated paths such as "/css-config.env" or...

Improper Handling of Length Parameter Inconsistency

Overview rack is a minimal, modular and adaptable interface for developing web applications in Ruby. By wrapping HTTP requests and responses in the simplest way possible, it unifies and distills the API for web servers, web frameworks, and software in between the so-called middleware into a singl...

CVE-2026-34524

SillyTavern is a locally installed user interface that allows users to interact with text generation large language models, image generation engines, and text-to-speech voice models. Prior to version 1.17.0, a path traversal vulnerability in chat endpoints allows an authenticated attacker to read...

CVE-2026-34730

Summary: CVE-2026-34730 affects Copier prior to version 9.14.1, where the optional _external_data feature allows template-controlled paths to load YAML files. This can enable destination-external reads, including parent-directory traversal (e.g., ../secret.yml) and absolute paths, exposing the co...

CVE-2026-34730 Copier `_external_data` allows path traversal and absolute-path local file read without unsafe mode

Copier is a library and CLI app for rendering project templates. Prior to version 9.14.1, Copier's externaldata feature allows a template to load YAML files using template-controlled paths. If untrusted templates are in scope, a malicious template can read attacker-chosen YAML-parseable local fil...

DEBIAN-CVE-2026-34831

Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Filesfail sets the Content-Length response header using Stringsize instead of Stringbytesize. When the response body contains multibyte UTF-8 characters, the declared Content-Length is smaller than the...

This vulnerability exists because authentication details are included in the encrypt...

CVE-2026-34830 Rack: Rack::Sendfile regex injection via HTTP_X_ACCEL_MAPPING header allows arbitrary file reads through nginx

Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Sendfilemapaccelpath interpolates the value of the X-Accel-Mapping request header directly into a regular expression when rewriting file paths for X-Accel-Redirect. Because the header value is not...

CVE-2026-34831

Rack: The vulnerability CVE-2026-34831 affects Rack::Files#fail, which uses String#size to set Content-Length instead of String#bytesize. When responses include multibyte UTF-8, Content-Length may be too small, causing HTTP framing issues and potential response desynchronization. The issue can be...
