@octokit/plugin-paginate-restnpmDescription
@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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @octokit/plugin-paginate-rest. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update @octokit/plugin-paginate-rest to 11.4.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-25288 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2025-25288 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2025-25288. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
