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

@octokit/request sends parameterized requests to GitHub’s APIs with sensible defaults in browsers and Node. Starting in version 1.0.0 and prior to versions 9.2.1 and 8.4.1, the regular expression `/<([^>]+)>; rel="deprecation"/` used to match the `link` header in HTTP responses is vulnerable to a ReDoS (Regular Expression Denial of Service) attack. This vulnerability arises due to the unbounded nature of the regex's matching behavior, which can lead to catastrophic backtracking when processing specially crafted input. An attacker could exploit this flaw by sending a malicious `link` header, resulting in excessive CPU usage and potentially causing the server to become unresponsive, impacting service availability. Versions 9.2.1 and 8.4.1 fix the issue.

CWE-1333

Octokit 安全漏洞

Octokit是GitHub API 的 Ruby 工具包。 Octokit 1.0.0版本至9.2.1之前版本存在安全漏洞，该漏洞源于正则表达式匹配行为的无限制性质，可能导致在处理特制输入时发生灾难性的回溯，容易受到正则表达式拒绝服务(ReDoS)攻击。
