undici vulnerable to Set-Cookie SameSite attribute downgrade via permissive substring matching...

GHSA-G8M3-5G58-FQ7M undici vulnerable to Set-Cookie SameSite attribute downgrade via permissive substring matching

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: -...

GHSA-VXPW-J846-P89Q undici WebSocket client vulnerable to denial of service via fragment count bypass

Impact The undici WebSocket client enforces maxPayloadSize on the cumulative byte count of fragments in a message but does not enforce a limit on the number of fragments. A malicious WebSocket server can stream many small or empty continuation frames that each pass per-frame and cumulative-size...

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...

undici vulnerable to cross-origin request routing via SOCKS5 proxy pool reuse...

GHSA-HM92-R4W5-C3MJ undici vulnerable to cross-origin request routing via SOCKS5 proxy pool reuse

Impact When using Socks5ProxyAgent, undici reuses a single connection pool across different origins without verifying that the pool's origin matches the requested origin. All requests are dispatched through the pool connected to the first origin, regardless of the intended destination. This cause...

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...
