GHSA-PP92-CRG2-GFV9 OAuth2::Client#request: Protocol-relative redirect Location overrides authority, leaking bearer Authorization to attacker host

Summary When an application uses OAuth2::Client typically via an OAuth2::AccessToken and the configured authorization server returns a redirect whose Location header is a protocol-relative URI of the form //attacker.example/leak, OAuth2::Clientrequest resolves the redirect with...

CVE-2026-54603 OAuth2::Client#request: Protocol-relative redirect Location overrides authority, leaking bearer Authorization to attacker host

OAuth2 is a Ruby wrapper for the OAuth 2.0 and 2.1 authorization frameworks, including OpenID Connect OIDC. From 0.4.0 to 2.0.21, a protocol-relative redirect Location returned to OAuth2::Clientrequest overrides the request authority, so the bearer Authorization header is sent to an...

CVE-2026-54605

Summary: CVE-2026-54605 affects the Ruby OAuth gem (versions 0.5.5–1.1.5). The flaw in OAuth::Consumer#token_request follows 300–399 redirects by parsing the raw Location header and recursing, which can mutate the gem’s site/configuration and disclose signed OAuth request metadata (including the ...

CVE-2026-54605

OAuth is a Ruby wrapper for the OAuth 1.0 and 1.0a protocols, providing clients and servers. From 0.5.5 to 1.1.5, OAuth::Consumertokenrequest parses the raw Location header of a 300 to 399 redirect returned by the OAuth server and follows the redirect recursively, which can mutate the consumer's...

CVE-2026-54605 OAuth: Cross-origin token-request redirects can expose signed request metadata

OAuth is a Ruby wrapper for the OAuth 1.0 and 1.0a protocols, providing clients and servers. From 0.5.5 to 1.1.5, OAuth::Consumertokenrequest parses the raw Location header of a 300 to 399 redirect returned by the OAuth server and follows the redirect recursively, which can mutate the consumer's...

CVE-2026-67183 TinyWeb 0.0.8 Memory Leak DoS via HTTP Request Handling

TinyWeb through 0.0.8 contains a memory leak vulnerability that allows unauthenticated attackers to exhaust available memory by sending ordinary well-formed HTTP requests. Each request causes HttpParser::execute to allocate Url objects, HttpHeaders objects, and HttpHeader instances via raw new...

CVE-2026-67181

Rouille 0.3.3 through 3.6.2 contains an HTTP request smuggling vulnerability that allows remote attackers to desynchronize HTTP message boundaries by exploiting improper header forwarding in the proxy implementation. The proxy in src/proxy.rs forwards the client's Transfer-Encoding header to...

CVE-2026-66753

tiny-http through 0.12.0 contains an HTTP header injection vulnerability that allows attackers to inject carriage return 0x0D and line feed 0x0A bytes into HTTP header values on both request and response sides due to insufficient validation in header parsing and serialization. Attackers can explo...

CVE-2026-66746

Rouille 0.4.0 through 3.6.2 contains an HTTP response splitting vulnerability that allows remote attackers to inject arbitrary response headers by embedding carriage return 0x0D or line feed 0x0A bytes into attacker-controlled input. Attackers can exploit percent-decoded query parameters reflecte...

CVE-2026-67182 Rouille 0.3.3 - 3.6.2 HTTP Request Smuggling via proxy Header Injection

Rouille 0.3.3 through 3.6.2 contains an HTTP request smuggling vulnerability that allows remote attackers to bypass access controls by injecting bare line feed characters 0x0A into client-supplied request header values that are copied verbatim to upstream connections without validation. Attackers...
