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...

Heimdall: Forwarded Header Injection via Unsanitized Host Header in Proxy Mode

Summary When Heimdall operates in proxy mode, it constructs the Forwarded HTTP header after executing the matched rule pipeline by inserting the incoming request's Host header value directly into the header string without sanitizing commas or semicolons. This allows an attacker to inject addition...

Cross-site Scripting

Apache ActiveMQ is vulnerable to Cross-site Scripting XSS. The vulnerability is due to MessageServlet copying JMS message properties directly into HTTP response headers without validation, allowing attackers to inject or overwrite security-related HTTP headers by crafting JMS messages with...

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...

CRLF Injection

Overview undici is an An HTTP/1.1 client, written from scratch for Node.js Affected versions of this package are vulnerable to CRLF Injection in the parseSetCookie. An attacker can inject arbitrary HTTP headers by supplying specially crafted percent-encoded values in the Set-Cookie header, which...
