Inefficient Regular Expression Complexity

Summary

The package @octokit/request-error is an error class for Octokit request errors. A Regular Expression Denial of Service (ReDoS) vulnerability exists in the processing of HTTP request headers. By sending an authorization header containing an excessively long sequence of spaces followed by a newline and "@", an attacker can exploit inefficient regular expression processing, leading to excessive resource consumption. This can significantly degrade server performance or cause a denial-of-service (DoS) condition, impacting availability. This issue affects versions prior to 5.1.1 and 6.0.x prior to 6.1.7.
