undici@5.26.1 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.

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.
