CVE-2026-0933

31
FAUCET Score

CVE-2026-0933 is a critical command injection vulnerability affecting Cloudflare Wrangler, specifically within the wrangler pages deploy command. The issue stems from improper sanitization of the --commit-hash parameter, allowing an attacker to execute arbitrary commands. With a CVSS score of 9.9 (CRITICAL), this vulnerability has a high impact, enabling attackers to exfiltrate environment variables or compromise CI runners, particularly in automated CI/CD pipelines where the parameter is populated from untrusted sources. While no active exploitation, public exploits, or significant community discussion have been observed, the vulnerability's severity necessitates immediate patching to Wrangler v4.59.1 (or higher) for v4 users, and v3.114.17 (or higher) for v3 users.
