| CVE-2026-48615 | 1 Nodejs | 1 Node.js | 2026-06-26 | N/A | 7.5 HIGH |
| A flaw in Node.js proxy tunnel error handling could expose proxy credentials in `ERR_PROXY_TUNNEL` error messages. When proxy credentials are embedded in the proxy URL, they may be exposed through error handling paths and captured by logs, diagnostics, or other error consumers. This vulnerability affects all supported release lines: **Node.js 22**, **Node.js 24**, and **Node.js 26**. | |||||
| CVE-2026-48935 | 1 Nodejs | 1 Node.js | 2026-06-26 | N/A | 3.3 LOW |
| A flaw in Node.js Permission API can cause a file metadata to be modified even on a path that was set as read-only with e.g. `--allow-fs-read`. This vulnerability affects all supported release lines: **Node.js 22**, **Node.js 24**, and **Node.js 26**. | |||||
| CVE-2026-48936 | 1 Nodejs | 1 Node.js | 2026-06-26 | N/A | 3.3 LOW |
| A flaw in Node.js Permission API can cause a local server to be started (via a Unix domain socket), even without the `--allow-net` permission. This vulnerability affects one supported release line: **Node.js 26**. | |||||
| CVE-2026-9675 | 1 Nodejs | 1 Undici | 2026-06-25 | N/A | 7.5 HIGH |
| Impact: The undici WebSocket client enforces maxPayloadSize per-frame but does not enforce the cumulative size of fragmented uncompressed messages. A malicious WebSocket server can stream many small fragments that each pass per-frame validation but collectively exceed the configured limit, causing unbounded memory growth in the client process. The result is memory exhaustion and a denial of service. Affected applications are those using the undici WebSocket client (new WebSocket(...)) that can be induced to connect to an attacker-controlled or compromised WebSocket endpoint. This is a regression specific to undici 8.1.0. The 6.25.0 line shipped the equivalent cumulative check from the start and is unaffected. The 7.x line never had the maxPayloadSize feature and is also unaffected. Patches: Upgrade to undici >= 8.5.0. Workarounds: No workaround is available. The fix must be applied through an upgrade. | |||||
| CVE-2026-11525 | 1 Nodejs | 1 Undici | 2026-06-25 | N/A | 3.7 LOW |
| 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, SameSite=NoneOfYourBusiness is parsed as None (the most permissive setting), and SameSite=StrictLax is parsed as Lax (a downgrade from Strict). Affected applications are those that consume Set-Cookie headers from server responses (for example via undici's fetch or proxy code paths) and then forward or rely on the parsed sameSite attribute. A malicious or non-compliant server can coerce the consumer's view of a cookie's SameSite policy to a weaker value, silently degrading the SameSite enforcement the cookie is supposed to provide. This was introduced in undici 5.15.0 when the cookies feature was added. Patches: Upgrade to undici v6.26.0, v7.28.0 or v8.5.0. Workarounds: After parsing a Set-Cookie header, validate that the resulting sameSite attribute is one of 'Strict', 'Lax', or 'None' (exact, case-insensitive) before forwarding or relying on it. | |||||
| CVE-2026-9678 | 1 Nodejs | 1 Undici | 2026-06-25 | N/A | 5.9 MEDIUM |
| 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 whitespace, so later comparisons against the literal authorization field name fail and the response is stored. In shared-cache mode, this allows a response containing one user's authenticated data to be served from cache to a subsequent caller, including an unauthenticated caller, when both requests resolve to the same cache key. Affected applications are those that explicitly enable the cache interceptor (interceptors.cache()) in shared mode, forward Authorization headers upstream, and receive cacheable responses with non-canonical qualified private or no-cache directives. Patches: Upgrade to undici v7.28.0 or v8.5.0. Workarounds: If upgrade is not immediately possible, disable shared-cache mode for traffic that includes Authorization headers, avoid caching responses to authenticated requests, or add Vary: Authorization upstream. | |||||
| CVE-2026-9679 | 1 Nodejs | 1 Undici | 2026-06-25 | N/A | 5.9 MEDIUM |
| 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 Set-Cookie header and then forward the parsed value into a response header (proxies, middleware, SSR frameworks) become vulnerable to HTTP response header injection: an attacker-controlled upstream can inject arbitrary Set-Cookie, Location, or Cache-Control headers into the application's downstream response, enabling session fixation, open redirect, or cache poisoning. Affected applications are those that use undici's cookie parsing (parseSetCookie, parseCookie, getSetCookies) and forward the parsed cookie value into a response header. This was introduced in undici 7.0.0 via PR #3789. Patches: Upgrade to undici v6.26.0, v7.28.0 or v8.5.0. Workarounds: If upgrade is not immediately possible, do not forward values returned by parseSetCookie/parseCookie/getSetCookies directly into response headers; sanitize the value first to strip or reject CR, LF, NUL, ;, and = bytes. | |||||
| CVE-2026-2581 | 1 Nodejs | 1 Undici | 2026-06-17 | N/A | 5.9 MEDIUM |
| This is an uncontrolled resource consumption vulnerability (CWE-400) that can lead to Denial of Service (DoS). In vulnerable Undici versions, when interceptors.deduplicate() is enabled, response data for deduplicated requests could be accumulated in memory for downstream handlers. An attacker-controlled or untrusted upstream endpoint can exploit this with large/chunked responses and concurrent identical requests, causing high memory usage and potential OOM process termination. Impacted users are applications that use Undici’s deduplication interceptor against endpoints that may produce large or long-lived response bodies. PatchesThe issue has been patched by changing deduplication behavior to stream response chunks to downstream handlers as they arrive (instead of full-body accumulation), and by preventing late deduplication when body streaming has already started. Users should upgrade to the first official Undici (and Node.js, where applicable) releases that include this patch. | |||||
| CVE-2026-22036 | 1 Nodejs | 1 Undici | 2026-06-17 | N/A | 5.9 MEDIUM |
| Undici is an HTTP/1.1 client for Node.js. Prior to 7.18.0 and 6.23.0, the number of links in the decompression chain is unbounded and the default maxHeaderSize allows a malicious server to insert thousands compression steps leading to high CPU usage and excessive memory allocation. This vulnerability is fixed in 7.18.0 and 6.23.0. | |||||
| CVE-2026-21637 | 1 Nodejs | 1 Node.js | 2026-06-17 | N/A | 7.5 HIGH |
| A flaw in Node.js TLS error handling allows remote attackers to crash or exhaust resources of a TLS server when `pskCallback` or `ALPNCallback` are in use. Synchronous exceptions thrown during these callbacks bypass standard TLS error handling paths (tlsClientError and error), causing either immediate process termination or silent file descriptor leaks that eventually lead to denial of service. Because these callbacks process attacker-controlled input during the TLS handshake, a remote client can repeatedly trigger the issue. This vulnerability affects TLS servers using PSK or ALPN callbacks across Node.js versions where these callbacks throw without being safely wrapped. | |||||
| CVE-2026-21636 | 1 Nodejs | 1 Node.js | 2026-06-17 | N/A | 10.0 CRITICAL |
| A flaw in Node.js's permission model allows Unix Domain Socket (UDS) connections to bypass network restrictions when `--permission` is enabled. Even without `--allow-net`, attacker-controlled inputs (such as URLs or socketPath options) can connect to arbitrary local sockets via net, tls, or undici/fetch. This breaks the intended security boundary of the permission model and enables access to privileged local services, potentially leading to privilege escalation, data exposure, or local code execution. * The issue affects users of the Node.js permission model on version v25. In the moment of this vulnerability, network permissions (`--allow-net`) are still in the experimental phase. | |||||
| CVE-2026-1527 | 1 Nodejs | 1 Undici | 2026-06-17 | N/A | 4.6 MEDIUM |
| ImpactWhen an application passes user-controlled input to the upgrade option of client.request(), an attacker can inject CRLF sequences (\r\n) to: * Inject arbitrary HTTP headers * Terminate the HTTP request prematurely and smuggle raw data to non-HTTP services (Redis, Memcached, Elasticsearch) The vulnerability exists because undici writes the upgrade value directly to the socket without validating for invalid header characters: // lib/dispatcher/client-h1.js:1121 if (upgrade) { header += `connection: upgrade\r\nupgrade: ${upgrade}\r\n` } | |||||
| CVE-2026-1525 | 1 Nodejs | 1 Undici | 2026-06-17 | N/A | 6.5 MEDIUM |
| Undici allows duplicate HTTP Content-Length headers when they are provided in an array with case-variant names (e.g., Content-Length and content-length). This produces malformed HTTP/1.1 requests with multiple conflicting Content-Length values on the wire. Who is impacted: * Applications using undici.request(), undici.Client, or similar low-level APIs with headers passed as flat arrays * Applications that accept user-controlled header names without case-normalization Potential consequences: * Denial of Service: Strict HTTP parsers (proxies, servers) will reject requests with duplicate Content-Length headers (400 Bad Request) * HTTP Request Smuggling: In deployments where an intermediary and backend interpret duplicate headers inconsistently (e.g., one uses the first value, the other uses the last), this can enable request smuggling attacks leading to ACL bypass, cache poisoning, or credential hijacking | |||||
| CVE-2025-59466 | 1 Nodejs | 1 Node.js | 2026-06-17 | N/A | 7.5 HIGH |
| We have identified a bug in Node.js error handling where "Maximum call stack size exceeded" errors become uncatchable when `async_hooks.createHook()` is enabled. Instead of reaching `process.on('uncaughtException')`, the process terminates, making the crash unrecoverable. Applications that rely on `AsyncLocalStorage` (v22, v20) or `async_hooks.createHook()` (v24, v22, v20) become vulnerable to denial-of-service crashes triggered by deep recursion under specific conditions. | |||||
| CVE-2025-59464 | 1 Nodejs | 1 Node.js | 2026-06-17 | N/A | 7.5 HIGH |
| A memory leak in Node.js’s OpenSSL integration occurs when converting `X.509` certificate fields to UTF-8 without freeing the allocated buffer. When applications call `socket.getPeerCertificate(true)`, each certificate field leaks memory, allowing remote clients to trigger steady memory growth through repeated TLS connections. Over time this can lead to resource exhaustion and denial of service. | |||||
| CVE-2025-55132 | 1 Nodejs | 1 Node.js | 2026-06-17 | N/A | 5.3 MEDIUM |
| A flaw in Node.js's permission model allows a file's access and modification timestamps to be changed via `futimes()` even when the process has only read permissions. Unlike `utimes()`, `futimes()` does not apply the expected write-permission checks, which means file metadata can be modified in read-only directories. This behavior could be used to alter timestamps in ways that obscure activity, reducing the reliability of logs. This vulnerability affects users of the permission model on Node.js v20, v22, v24, and v25. | |||||
| CVE-2025-23084 | 2 Microsoft, Nodejs | 2 Windows, Node.js | 2026-06-17 | N/A | 5.5 MEDIUM |
| A vulnerability has been identified in Node.js, specifically affecting the handling of drive names in the Windows environment. Certain Node.js functions do not treat drive names as special on Windows. As a result, although Node.js assumes a relative path, it actually refers to the root directory. On Windows, a path that does not start with the file separator is treated as relative to the current directory. This vulnerability affects Windows users of `path.join` API. | |||||
| CVE-2024-3566 | 6 Haskell, Microsoft, Nodejs and 3 more | 6 Process Library, Windows, Node.js and 3 more | 2026-06-17 | N/A | 9.8 CRITICAL |
| A command inject vulnerability allows an attacker to perform command injection on Windows applications that indirectly depend on the CreateProcess function when the specific conditions are satisfied. | |||||
| CVE-2024-30261 | 2 Fedoraproject, Nodejs | 2 Fedora, Undici | 2026-06-17 | N/A | 2.6 LOW |
| Undici is an HTTP/1.1 client, written from scratch for Node.js. An attacker can alter the `integrity` option passed to `fetch()`, allowing `fetch()` to accept requests as valid even if they have been tampered. This vulnerability was patched in version(s) 5.28.4 and 6.11.1. | |||||
| CVE-2024-30260 | 2 Fedoraproject, Nodejs | 2 Fedora, Undici | 2026-06-17 | N/A | 3.9 LOW |
| Undici is an HTTP/1.1 client, written from scratch for Node.js. Undici cleared Authorization and Proxy-Authorization headers for `fetch()`, but did not clear them for `undici.request()`. This vulnerability was patched in version(s) 5.28.4 and 6.11.1. | |||||
