Description

Cloudflare was recently notified by external researchers of vulnerabilities in this archived repository, including a remote code execution issue in `src/index.ts` reachable from certain GitHub Actions workflow configurations. Successful exploitation may expose workflow secrets such as CLOUDFLARE_API_TOKEN and GITHUB_TOKEN to an attacker. Because this repository has been deprecated since 2024, Cloudflare will not be issuing patches. To remediate this issue, we recommend migrating to `cloudflare/wrangler-action` immediately. Consumers who have already migrated are not affected.

Sunset Date

The cloudflare/pages-action repository will be removed on 2026-09-18. Consumers must complete migration before 18th September to avoid CI disruption.

Affected Versions

All published versions of cloudflare/pages-action, including consumers pinned to the v1 moving tag.

Patched Versions

None. This repository will not receive further updates, including security patches.

Resolution / Migration Path

Migrate all workflows using cloudflare/pages-action to `cloudflare/wrangler-action` before 2026-09-18. Refer to the wrangler-action README for the equivalent step configuration and migration guidance.
