@octokit/request

@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.

The Request package through 2.88.1 for Node.js allows a bypass of SSRF mitigations via an attacker-controller server that does a cross-protocol redirect (HTTP to HTTPS, or HTTPS to HTTP). NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
