SUSE CVE-2026-34786

Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Staticapplicablerules evaluates several headerrules types against the raw URL-encoded PATHINFO, while the underlying file-serving path is decoded before the file is served. As a result, a request for a...

SUSE CVE-2026-34826

Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Utils.getbyteranges parses the HTTP Range header without limiting the number of individual byte ranges. Although the existing fix for CVE-2024-26141 rejects ranges whose total byte coverage exceeds the...

SUSE CVE-2026-34835

Rack is a modular Ruby web server interface. From versions 3.0.0.beta1 to before 3.1.21, and 3.2.0 to before 3.2.6, Rack::Request parses the Host header using an AUTHORITY regular expression that accepts characters not permitted in RFC-compliant hostnames, including /, ?, , and @. Because req.hos...

CVE-2026-34715

ewe is a Gleam web server. Prior to version 3.0.6, the encodeheaders function in src/ewe/internal/encoder.gleam directly interpolates response header keys and values into raw HTTP bytes without validating or stripping CRLF \r\n sequences. An application that passes user-controlled data into...

Haraka is a Node.js mail server. Prior to version 3.1.4, sending an email with proto: as a header name crashes the Haraka worker process. This issue has been patched in version 3.1.4...

Server-side Request Forgery (SSRF)

Overview prompts.chat is a Developer toolkit for AI prompts - build, validate, parse, and connect to prompts.chat Affected versions of this package are vulnerable to Server-side Request Forgery SSRF via the token parameter in the Fal.ai media status polling flow. An attacker can access sensitive...

fast-jwt accepts unknown `crit` header extensions (RFC 7515 violation)

Summary fast-jwt does not validate the crit Critical Header Parameter defined in RFC 7515 §4.1.11. When a JWS token contains a crit array listing extensions that fast-jwt does not understand, the library accepts the token instead of rejecting it. This violates the MUST requirement in the RFC. ---...

Not Failing Securely ('Failing Open')

Overview fast-jwt is a Fast JSON Web Token implementation Affected versions of this package are vulnerable to Not Failing Securely 'Failing Open' due to improper validation of the crit header parameter. An attacker can bypass intended authorization policies by crafting a signed token with unknown...

GHSA-CXJ8-GGF2-P57C Signal K Server: OAuth Authorization Code Theft via Unvalidated Host Header in OIDC Flow

Summary SignalK Server contains a code-level vulnerability in its OIDC login and logout handlers where the unvalidated HTTP Host header is used to construct the OAuth2 redirecturi. Because the redirectUri configuration is silently unset by default, an attacker spoof the Host header to steal OAuth...

CVE-2026-22664

prompts.chat prior to commit 30a8f04 contains a server-side request forgery vulnerability in the Fal.ai media status polling feature that allows authenticated users to perform arbitrary outbound requests by supplying attacker-controlled URLs in the token parameter. Attackers can exploit the lack ...

CVE-2026-26962

A flaw was found in Rack, a modular Ruby web server interface. Rack::Multipart::Parser incorrectly processes folded multipart part headers, failing to remove embedded carriage return and line feed CRLF characters. This can lead to applications that reuse these parsed values in HTTP response heade...

CVE-2026-34826

A flaw was found in Rack. A remote attacker can exploit this by sending a specially crafted HTTP Range header containing numerous small, overlapping byte ranges. This can cause disproportionate consumption of CPU, memory, I/O, and bandwidth resources. The result is a Denial of Service DoS conditi...

CVE-2026-34831

A flaw was found in Rack. A remote attacker can exploit this vulnerability by requesting a non-existent path containing percent-encoded UTF-8 characters. This causes Rack::Filesfail to incorrectly calculate the Content-Length header, using Stringsize instead of Stringbytesize for multibyte...
