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...

Origin Validation Error

Overview signalk-server is an An implementation of a Signal K server for boats. Affected versions of this package are vulnerable to Origin Validation Error via the construction of the redirectUri and fullPostLogoutUri using an unvalidated Host header in the OIDC authentication and logout processe...

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...

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-2026-22664

The CVE-2026-22664 issue affects prompts.chat with an SSRF in Fal.ai media status polling prior to commit 30a8f04. Authenticated users can supply attacker-controlled URLs in the token parameter to trigger arbitrary outbound requests, potentially exposing the FAL_API_KEY in the Authorization heade...

CVE-2026-32762

A flaw was found in Rack, a modular Ruby web server interface. This vulnerability arises from improper parsing of the RFC 7239 Forwarded header, where semicolons within quoted values are incorrectly interpreted as delimiters. An attacker can exploit this by crafting a malicious Forwarded header,...

CVE-2026-34835

A flaw was found in Rack. A remote attacker could exploit this by sending a specially crafted Host header containing characters not permitted in standard hostnames. This malformed header bypasses hostname validation in applications using Rack::Request, leading to host header poisoning. This can...
