undici@4.12.2 vulnerabilities

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to Improper Authorization due to improper handling of Proxy-Authorization headers during cross-origin redirects in certain methods. An attacker can exploit this behavior by inducing a victim to make a request that triggers a cross-origin redirect, potentially leaking sensitive information contained in the Proxy-Authorization header.

Upgrade undici to version 5.28.4, 6.11.1 or higher.

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to Improper Access Control due to the integrity option passed to fetch(). An attacker can alter this option, allowing fetch() to accept requests as valid even if they have been tampered with.

Upgrade undici to version 5.28.4, 6.11.1 or higher.

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to Permissive Cross-domain Policy with Untrusted Domains due to not clearing Proxy-Authentication headers on cross-origin redirects. An attacker can intercept the improperly cleared headers.

Upgrade undici to version 5.28.3, 6.6.1 or higher.

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to Information Exposure during the Cookie headers handling process. An attacker can potentially leak sensitive information to a third-party site or a malicious actor who can control the redirection target (i.e., an open redirector) by exploiting the disconnect between the spec's assumptions and the implementation of fetch.

Note:

This is only exploitable if the attacker can control the redirection target.

Upgrade undici to version 5.26.2 or higher.

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS) via the Headers.set() and Headers.append() methods, when untrusted values are passed into the functions. This is due to the inefficient regular expression used to normalize the values in the headerValueNormalize() utility function.

Upgrade undici to version 5.19.1 or higher.

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to CRLF Injection due to missing protection for the host HTTP header.

Upgrade undici to version 5.19.1 or higher.

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to CRLF Injection when using unsanitized input as request headers (for example, inside the content-type header).

Upgrade undici to version 5.8.2 or higher.

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) when an application takes in unsanitized user input into the path/pathname option of undici.request.

Upgrade undici to version 5.8.2 or higher.

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to Information Exposure by not clearing cookie headers upon third party redirect.

Note: This is only exploitable when maxRedirections is changed from its default value of 0.

Upgrade undici to version 5.8.0 or higher.

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to CRLF Injection in lib/core/request.js that allows HTTP requests to be injected via unexpected CRLF (\r\n) sequences in request path, method, and headers received from untrusted sources.

Upgrade undici to version 5.8.0 or higher.

undici is an An HTTP/1.1 client, written from scratch for Node.js

Affected versions of this package are vulnerable to Improper Certificate Validation due to Undici.ProxyAgent missing verification of the remote server's certificate, which leads to exposure of all the requests and responses data to the proxy.

Upgrade undici to version 5.5.1 or higher.
