undici 1.2.1 vulnerabilities

Known vulnerabilities in the undici package. This does not include vulnerabilities belonging to this package’s dependencies.

Vulnerability	Vulnerable Version
L Improper Authorization 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. How to fix Improper Authorization? Upgrade `undici` to version 5.28.4, 6.11.1 or higher.	<5.28.4>=6.0.0 <6.11.1
L Improper Access Control 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. How to fix Improper Access Control? Upgrade `undici` to version 5.28.4, 6.11.1 or higher.	<5.28.4>=6.0.0 <6.11.1
L Permissive Cross-domain Policy with Untrusted Domains 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. How to fix Permissive Cross-domain Policy with Untrusted Domains? Upgrade `undici` to version 5.28.3, 6.6.1 or higher.	<5.28.3>=6.0.0 <6.6.1
L Information Exposure 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. How to fix Information Exposure? Upgrade `undici` to version 5.26.2 or higher.	<5.26.2
H Regular Expression Denial of Service (ReDoS) 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. How to fix Regular Expression Denial of Service (ReDoS)? Upgrade `undici` to version 5.19.1 or higher.	<5.19.1
M CRLF Injection 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). How to fix CRLF Injection? Upgrade `undici` to version 5.8.2 or higher.	<5.8.2
M Server-side Request Forgery (SSRF) 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`. How to fix Server-side Request Forgery (SSRF)? Upgrade `undici` to version 5.8.2 or higher.	<5.8.2
L Information Exposure 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. How to fix Information Exposure? Upgrade `undici` to version 5.8.0 or higher.	<5.8.0
M CRLF Injection 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. How to fix CRLF Injection? Upgrade `undici` to version 5.8.0 or higher.	<5.8.0
