CVE-2026-9678

Undici (node) vulnerability CVE-2026-9678: in shared-cache mode, the cache interceptor may misclassify responses as cacheable when Cache-Control uses whitespace-padded private/no-cache directives (e.g., private=" authorization" or no-cache="\tauthorization"). The whitespace is preserved by the pa...

CVE-2026-47774 Envoy vulnerable to HTTP/2 memory exhaustion via cookie header size bypass and HPACK amplification

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-2026-47774

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...

CVE-2026-9679 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...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the mtarnext function. An attacker can cause the process to enter an infinite loop and consume excessive CPU resources by providing a specially crafted tar archive that manipulates the header size fiel...

netty-codec-http2: Netty: Denial of Service due to HTTP/2 max header size handling

A flaw was found in Netty, a network application framework. A remote attacker can exploit a vulnerability in the HTTP/2 Hypertext Transfer Protocol version 2 maximum header size handling. By sending a specific SETTINGSMAXHEADERLISTSIZE setting, an attacker can cause Netty to produce an exception...

netty-codec-haproxy: Netty-codec-haproxy: Denial of Service via malformed HAProxy message

A flaw was found in netty-codec-haproxy, a component of the Netty network application framework. A remote attacker can exploit this vulnerability by sending a specially crafted HAProxy message with a malformed PP2TYPESSL TLV Type-Length-Value header. This can lead to an IndexOutOfBoundsException...
