CVE-2025-25288: @octokit/plugin-paginate-rest has a Regular Expression in iterator that Leads to ReDoS Vulnerability Due to Catastrophic Backtracking
Description
@octokit/plugin-paginate-rest is the Octokit plugin to paginate REST API endpoint responses. For versions starting in 1.0.0 and prior to 11.4.1 of the npm package `@octokit/plugin-paginate-rest`, when calling `octokit.paginate.iterator()`, a specially crafted `octokit` instance—particularly with a malicious `link` parameter in the `headers` section of the `request`—can trigger a ReDoS attack. Version 11.4.1 contains a fix for the issue.
