Description
A flaw was found in the Undici node package due to the occurrence of Cross-origin requests, possibly leading to a cookie header leakage. By default, cookie headers are forbidden request headers, and they must be enabled. This flaw allows a malicious user to access this leaked cookie if they have control of the redirection.
Statement
Since this requires a non-standard configuration, as well as control of the redirection, Red Hat rates this as having a Low impact.
Red Hat Developer Hub has included a fix for this.
