CVE-2026-84933

undici (Node.js HTTP client) has a vulnerability in its cache interceptor that fails to handle the Set-Cookie response header in its cache path—neither refusing to store nor stripping it. In shared cache mode (the default), a cacheable response carrying a Set-Cookie header is stored and re-served...

CVE-2026-84933

undici's cache interceptor does not handle the Set-Cookie response header anywhere in its cache path, so it neither refuses to store nor strips that header. In shared cache mode, which is the default, an otherwise cacheable response that carries a Set-Cookie header, for example one marked with a...

secure cookie attribute bypass with tab

A Set-Cookie: header using tab horizontal tab, ASCII code 9 instead of space ascii code 32 immediately before the Secure attribute causes curl to store the cookie without its Secure flag. The cookie might then wrongfully be sent over plaintext HTTP on subsequent requests to the same host...

A Set-Cookie: header using tab horizontal tab, ASCII code 9 instead of space ascii code 32 immediately before the Secure attribute causes curl to store the cookie without its Secure flag. The cookie might then wrongfully be sent over plaintext HTTP on subsequent requests to the same host...

domain-scoped PSL domain cookie

When libpsl support is enabled, libcurl fails to enforce the Public Suffix List boundary check when processing a Set-Cookie header where the Domain attribute explicitly matches an origin host that is itself a public suffix e.g., Domain=co.uk set by co.uk. Instead of coercing it into a strict...

CVE-2026-66746-HTTP-Response-Splitting-via-Unvalidated-Response-Header-Values-rouille-

安全公告：未经验证的响应头值导致的 HTTP 响应拆分（rouille） 分配的 CVE ID： CVE-2026-66746 摘要 rouille 在将响应头值写入客户端时，不会检查其中是否包含 回车符或换行符。因此，应用程序若将受攻击者影响的文本 放入响应头值，就会在线路上发出额外的响应头，甚至是 整整第二个 HTTP 响应。 rouille 的两个特性使该漏洞在普通代码中也能触达。Request::getparam 会进行百分号解码，因此查询字符串中的 %0d%0a 会变成真正的 CRLF。 而 session::session 会将客户端自己的 Cookie 值复制到...

CVE-2026-67353

A flaw was found in guzzlehttp/guzzle. A remote attacker can exploit this vulnerability by sending an excessive number of large 'Set-Cookie' header fields from a malicious server. This causes the application's CookieJar to store an unbounded amount of data in memory, leading to resource exhaustio...

undici: undici: Cross-user cookie disclosure via Set-Cookie caching

A flaw was found in undici. The software's caching mechanism, when operating in shared cache mode, improperly stores responses that include 'Set-Cookie' headers. This oversight allows an untrusted server to inject cookies into cached responses. Consequently, sensitive cookie information from one...
