CVE-2025-25289

@octokit/request-error has a Regular Expression in index that Leads to ReDoS Vulnerability Due to Catastrophic Backtracking

Description

@octokit/request-error is an error class for Octokit request errors. Starting in version 1.0.0 and prior to version 6.1.7, 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. Version 6.1.7 contains a fix for the issue.
