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...

GHSA-35P6-XMWP-9G52 undici vulnerable to HTTP response queue poisoning via keep-alive socket reuse

Impact Undici's HTTP/1.1 client is vulnerable to response queue poisoning on reused keep-alive sockets. An attacker-controlled upstream server can inject an unsolicited HTTP/1.1 response onto an idle socket after a request completes. When the client dispatches the next request on that socket, it...

SUSE 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,...

undici vulnerable to TLS certificate validation bypass via dropped requestTls in SOCKS5 ProxyAgent

Impact undici's ProxyAgent silently drops the requestTls option when configured with a SOCKS5 proxy URI socks5:// or socks://. The target HTTPS connection through the SOCKS5 tunnel falls back to Node's default trust store, ignoring user-configured ca, cert, key, rejectUnauthorized, and servername...

GHSA-PR7R-676H-XCF6 undici vulnerable to cross-user information disclosure via shared cache whitespace bypass

Impact Undici's cache interceptor incorrectly classifies some responses as cacheable when the upstream Cache-Control header uses whitespace-padded qualified private or no-cache field names such as private=" authorization" or no-cache="\tauthorization". The parser preserves the surrounding...

CVE-2026-6734

This can lead to cross-origin request routing, where sensitive credentials and data intended for one destination are sent to another. Consequently, responses from...

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...
