CVE-2026-11325Network attack vector

Remote code execution via unquoted version input

Published Aug 12, 2026 · Updated Aug 12, 2026

OS command injection in all published versions of Cloudflare Pages GitHub Action allows remote attackers to execute code on a workflow runner. The src/index.ts deployment path interpolates the wranglerVersion input directly into an npx package specifier executed by shellac without constraining shell metacharacters. Exploitation requires a workflow configuration that lets attacker-controlled data reach that input and runs the action; successful execution can expose workflow secrets and alter or interrupt the runner job.
