CVE-2025-25285: Octokit Endpoint.js

Medium severity, CVSS 5.3. EPSS: 0.6% chance of exploitation in the next 30 days.

@octokit/endpoint turns REST API endpoints into generic request options. Starting in version 4.1.0 and prior to version 10.1.3, by crafting specific `options` parameters, the `endpoint.parse(options)` call can be triggered, leading to a regular expression denial-of-service (ReDoS) attack. This causes the program to hang and results in high CPU utilization. The issue occurs in the `parse` function within the `parse.ts` file of the npm package `@octokit/endpoint`. Version 10.1.3 contains a patch for the issue.

Affected products

• Octokit Endpoint.js: from 4.1.0, before 10.1.3 (fixed in 10.1.3)
