GHSA-P88M-4JFJ-68FV undici vulnerable to HTTP header injection via Set-Cookie percent-decoding

Impact undici's cookie parser in parseSetCookie percent-decodes cookie values via qsUnescape, turning encoded sequences like %0D%0A, %00, %3B, and %3D into their literal byte equivalents. RFC 6265 §5.4 does not specify any decoding and browsers do not decode either. Applications that parse a...

CVE-2026-47774

Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to versions 1.35.11, 1.36.7, 1.37.3, and 1.38.1, a vulnerability in Envoy's HTTP/2 downstream request processing allows an unauthenticated remote client to trigger excessive memory consumption, potentiall...

CVE-2026-11525

Impact: When undici parses a Set-Cookie header, it accepts any SameSite attribute value that contains Strict, Lax, or None as a substring, rather than the case-insensitive exact match specified by RFC 6265. Non-spec values are silently mapped to one of the three standard tokens. For example,...

CVE-2026-47774

CVE-2026-47774 affects Envoy prior to versions 1.35.11, 1.36.7, 1.37.3, and 1.38.1. A vulnerability in HTTP/2 downstream request processing combines two issues: (1) cookie header bytes are not fully accounted for during request header size validation, and (2) HPACK header limits are enforced on e...

CVE-2026-9679

undici vulnerability CVE-2026-9679 affects the cookie parsing paths (parseSetCookie, parseCookie, getSetCookies). The cookie parser percent-decodes values (via qsUnescape), turning sequences like %0D%0A, %00, %3B, and %3D into literal bytes. RFC 6265 §5.4 does not require decoding and browsers do...

Tornado: Authorization header forwarded across cross-origin redirects in SimpleAsyncHTTPClient

Summary When SimpleAsyncHTTPClient follows a 3xx redirect, it shallow-copies the original HTTPRequest, rewrites the URL, decrements maxredirects, and removes only the Host header. It does not clear Authorization, authusername, authpassword, or authmode when the redirect target changes origin. As ...
