This may lead to false positive errors during subsequent cryptographic operations that happen to be on the same thread. This in turn could be used to cause a denial of ser

CVE-2023-38552 [HIGH] CWE-345 CVE-2023-38552: When the Node.js policy feature checks the integrity of a resource against a trusted manifest, the a When the Node.js policy feature checks the integrity of a resource against a trusted manifest, the application can intercept the operation and return a forged checksum to the node's policy implementation, thus effectively disabling the integrity check. Impacts: This vulnerability affects all users using the experimental policy mechanism in all active

CVE-2025-23083 [HIGH] CWE-284 CVE-2025-23083: With the aid of the diagnostics_channel utility, an event can be hooked into whenever a worker threa With the aid of the diagnostics_channel utility, an event can be hooked into whenever a worker thread is created. This is not limited only to workers but also exposes internal workers, where an instance of them can be fetched, and its constructor can be grabbed and reinstated for malicious usage. This vulnerability affects Permission Model users (--p

CVE-2025-59464 [HIGH] CWE-400 CVE-2025-59464: A memory leak in Node.js’s OpenSSL integration occurs when converting `X.509` certificate fields to 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 t

CVE-2021-44532 [MEDIUM] CWE-296 CVE-2021-44532: Node.js < 12.22.9, < 14.18.3, < 16.13.2, and < 17.3.1 converts SANs (Subject Alternative Names) to a 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 o

CVE-2023-30584 [HIGH] CWE-22 CVE-2023-30584: A vulnerability has been discovered in Node.js version 20, specifically within the experimental perm A vulnerability has been discovered in Node.js version 20, specifically within the experimental permission model. This flaw relates to improper handling of path traversal bypass when verifying file permissions. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

CVE-2025-23167 [MEDIUM] CWE-444 CVE-2025-23167: A flaw in Node.js 20's HTTP parser allows improper termination of HTTP/1 headers using `\r\n\rX` ins A flaw in Node.js 20's HTTP parser allows improper termination of HTTP/1 headers using `\r\n\rX` instead of the required `\r\n\r\n`. This inconsistency enables request smuggling, allowing attackers to bypass proxy-based access controls and submit unauthorized requests. The issue was resolved by upgrading `llhttp` to version 9, which enforces correc

CVE-2022-32223 [HIGH] CWE-427 CVE-2022-32223: Node.js is vulnerable to Hijack Execution Flow: DLL Hijacking under certain conditions on Windows pl 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` w

CVE-2024-22017 [HIGH] CWE-250 CVE-2024-22017: setuid() does not affect libuv's internal io_uring operations if initialized before the call to setu setuid() does not affect libuv's internal io_uring operations if initialized before the call to setuid(). This allows the process to perform privileged operations despite presumably having dropped such privileges through a call to setuid(). This vulnerability affects all users using version greater or equal than Node.js 18.18.0, Node.js 20.4.0 and Nod

CVE-2021-22960 [MEDIUM] CWE-444 CVE-2021-22960: The parse function in llhttp < 2.1.4 and < 6.0.6. ignores chunk extensions when parsing the body of 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.

CVE-2021-44533 [MEDIUM] CWE-295 CVE-2021-44533: Node.js < 12.22.9, < 14.18.3, < 16.13.2, and < 17.3.1 did not handle multi-value Relative Distinguis 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 allo

CVE-2021-22939 [MEDIUM] CWE-295 CVE-2021-22939: If the Node.js https API was used incorrectly and "undefined" was in passed for the "rejectUnauthori 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.

CVE-2024-27982 [MEDIUM] CWE-444 CVE-2024-27982: The team has identified a critical vulnerability in the http server of the most recent version of No The team has identified a critical vulnerability in the http server of the most recent version of Node, where malformed headers can lead to HTTP request smuggling. Specifically, if a space is placed before a content-length header, it is not interpreted correctly, enabling attackers to smuggle in a second request within the body of the first.

CVE-2021-22959 [MEDIUM] CWE-444 CVE-2021-22959: The parser in accepts requests with a space (SP) right after the header name before the colon. This 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.

CVE-2022-35256 [MEDIUM] CWE-444 CVE-2022-35256: The llhttp parser in the http module in Node v18.7.0 does not correctly handle header fields that ar The llhttp parser in the http module in Node v18.7.0 does not correctly handle header fields that are not terminated with CLRF. This may result in HTTP Request Smuggling.

CVE-2024-22020 [MEDIUM] CWE-94 CVE-2024-22020: A security flaw in Node.js allows a bypass of network import restrictions. By embedding non-network A security flaw in Node.js allows a bypass of network import restrictions. By embedding non-network imports in data URLs, an attacker can execute arbitrary code, compromising system security. Verified on various platforms, the vulnerability is mitigated by forbidding data URLs in network imports. Exploiting this flaw can violate network import securit

CVE-2024-21890 [MEDIUM] CVE-2024-21890: The Node.js Permission Model does not clarify in the documentation that wildcards should be only use The Node.js Permission Model does not clarify in the documentation that wildcards should be only used as the last character of a file path. For example: ``` --allow-fs-read=/home/node/.ssh/*.pub ``` will ignore `pub` and give access to everything after `.ssh/`. This misleading documentation affects all users using the experimental permission model in Node
