CVE-2026-11525

A flaw was found in undici. When undici processes Set-Cookie headers, it incorrectly interprets the SameSite attribute, accepting partial matches instead of exact ones. This allows a malicious server to downgrade a cookie's SameSite policy to a less secure setting, potentially leading to unintend...

CVE-2026-9679

A flaw was found in undici. The cookie parser in the parseSetCookie function incorrectly decodes cookie values, which is contrary to standard specifications. This vulnerability allows an attacker-controlled upstream to inject arbitrary HTTP response headers, such as Set-Cookie, Location, or...

CVE-2026-53871

Hermes WebUI before 0.51.368 contains an authorization bypass vulnerability in the getprofilecookie function that accepts unauthenticated profile names from the hermesprofile cookie. An authenticated attacker can forge the hermesprofile cookie value to bypass profile-scoped authorization checks a...

Cross-Origin Resource Sharing (CORS) Misconfiguration

hono is vulnerable to Cross-Origin Resource Sharing CORS Misconfiguration. The vulnerability is due to reflecting arbitrary Origin headers while allowing credentials when no explicit origin is configured, which allows an attacker-controlled website to make authenticated cross-origin requests and...

Permissive List of Allowed Inputs

Overview undici is an An HTTP/1.1 client, written from scratch for Node.js Affected versions of this package are vulnerable to Permissive List of Allowed Inputs via permissive substring matching in the Set-Cookie attribute parsing. An attacker can weaken cookie SameSite enforcement by crafting a...

CVE-2026-9679

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,...

GHSA-MX8G-39Q3-5C79 webpack-dev-server vulnerable to HMR WebSocket interception via permissive user proxies

Impact When a user-configured proxy on webpack-dev-server has a broad context e.g. / and ws: true, it also intercepts the dev server's own HMR WebSocket and forwards it to the proxy target. This leaks the browser's cookies and Origin header to the backend, bypasses the dev server's Host/Origin...
