CVE-2026-111497
Vulnerabilities: 148
A weak randomness in WebCrypto keygen vulnerability exists in Node.js 18 due to a change with EntropySource() in SecretKeyGenTraits::DoKeyGen() in src/crypto/crypto_keygen.cc. There are two problems with this: 1) It does not check the return value, it assumes EntropySource() always succeeds, but it can (and sometimes will) fail. 2) The random data returned byEntropySource() may not be cryptographically strong and therefore not suitable as keying material.
Node.js is vulnerable to Hijack Execution Flow: DLL Hijacking under certain conditions on Windows platforms.This vulnerability can be exploited if the victim has the following dependencies on a Windows machine:* OpenSSL has been installed and “C:\Program Files\Common Files\SSL\openssl.cnf” exists.Whenever the above conditions are present, `node.exe` will search for `providers.dll` in the current user directory.After that, `node.exe` will try to search for `providers.dll` by the DLL Search Order in Windows.It is possible for an attacker to place the malicious file `providers.dll` under a variety of paths and exploit this vulnerability.
A cryptographic vulnerability exists on Node.js on linux in versions of 18.x prior to 18.40.0 which allowed a default path for openssl.cnf that might be accessible under some circumstances to a non-admin user instead of /etc/ssl as was the case in versions prior to the upgrade to OpenSSL 3.
The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not correctly handle multi-line Transfer-Encoding headers. This can lead to HTTP Request Smuggling (HRS).
The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not strictly use the CRLF sequence to delimit HTTP requests. This can lead to HTTP Request Smuggling (HRS).
The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not correctly parse and validate Transfer-Encoding headers and can lead to HTTP Request Smuggling (HRS).
A OS Command Injection vulnerability exists in Node.js versions <14.20.0, <16.20.0, <18.5.0 due to an insufficient IsAllowedHost check that can easily be bypassed because IsIPAddress does not properly check if an IP address is invalid before making DBS requests allowing rebinding attacks.
Node.js < 12.22.9, < 14.18.3, < 16.13.2, and < 17.3.1 did not handle multi-value Relative Distinguished Names correctly. Attackers could craft certificate subjects containing a single-value Relative Distinguished Name that would be interpreted as a multi-value Relative Distinguished Name, for example, in order to inject a Common Name that would allow bypassing the certificate subject verification.Affected versions of Node.js that do not accept multi-value Relative Distinguished Names and are thus not vulnerable to such attacks themselves. However, third-party code that uses node's ambiguous presentation of certificate subjects may be vulnerab
Node.js < 12.22.9, < 14.18.3, < 16.13.2, and < 17.3.1 converts SANs (Subject Alternative Names) to a string format. It uses this string to check peer certificates against hostnames when validating connections. The string format was subject to an injection vulnerability when name constraints were used within a certificate chain, allowing the bypass of these name constraints.Versions of Node.js with the fix for this escape SANs containing the problematic characters in order to prevent the injection. This behavior can be reverted through the --security-revert command-line option.
Accepting arbitrary Subject Alternative Name (SAN) types, unless a PKI is specifically defined to use a particular SAN type, can result in bypassing name-constrained intermediates. Node.js < 12.22.9, < 14.18.3, < 16.13.2, and < 17.3.1 was accepting URI SAN types, which PKIs are often not defined to use. Additionally, when a protocol allows URI SANs, Node.js did not match the URI correctly.Versions of Node.js with the fix for this disable the URI SAN type when checking a certificate against a hostname. This behavior can be reverted through the --security-revert command-line option.
Due to the formatting logic of the "console.table()" function it was not safe to allow user controlled input to be passed to the "properties" parameter while simultaneously passing a plain object with at least one property as the first parameter, which could be "__proto__". The prototype pollution has very limited control, in that it only allows an empty string to be assigned to numerical keys of the object prototype.Node.js >= 12.22.9, >= 14.18.3, >= 16.13.2, and >= 17.3.1 use a null protoype for the object these properties are being assigned to.
The parser in accepts requests with a space (SP) right after the header name before the colon. This can lead to HTTP Request Smuggling (HRS) in llhttp < v2.1.4 and < v6.0.6.
The parse function in llhttp < 2.1.4 and < 6.0.6. ignores chunk extensions when parsing the body of chunked requests. This leads to HTTP Request Smuggling (HRS) under certain conditions.
Node.js before 16.6.0, 14.17.4, and 12.22.4 is vulnerable to a use after free attack where an attacker might be able to exploit the memory corruption, to change process behavior.
Node.js before 16.6.1, 14.17.5, and 12.22.5 is vulnerable to a use after free attack where an attacker might be able to exploit the memory corruption, to change process behavior.
If the Node.js https API was used incorrectly and "undefined" was in passed for the "rejectUnauthorized" parameter, no error was returned and connections to servers with an expired certificate would have been accepted.
Node.js before 16.6.0, 14.17.4, and 12.22.4 is vulnerable to Remote Code Execution, XSS, Application crashes due to missing input validation of host names returned by Domain Name Servers in Node.js dns library which can lead to output of wrong hostnames (leading to Domain Hijacking) and injection vulnerabilities in applications using the library.
Node.js before 16.4.1, 14.17.2, and 12.22.2 is vulnerable to local privilege escalation attacks under certain conditions on Windows platforms. More specifically, improper configuration of permissions in the installation directory allows an attacker to perform two different escalation attacks: PATH and DLL hijacking.
Node.js before 16.4.1, 14.17.2, 12.22.2 is vulnerable to an out-of-bounds read when uv__idna_toascii() is used to convert strings to ASCII. The pointer p is read and increased without checking whether it is beyond pe, with the latter holding a pointer to the end of the buffer. This can lead to information disclosures or crashes. This function can be triggered via uv_getaddrinfo().
Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable to a denial of service attack when too many connection attempts with an 'unknownProtocol' are established. This leads to a leak of file descriptors. If a file descriptor limit is configured on the system, then the server is unable to accept new connections and prevent the process also from opening, e.g. a file. If no file descriptor limit is configured, then this lead to an excessive memory usage and cause the system to run out of memory.
