CVE-2026-0933
CriticalSummary
A command injection vulnerability (CWE-78) has been found in the `wrangler pages deploy` command. The issue occurs because the `--commit-hash` parameter is passed directly to a shell command without proper validation or sanitization, allowing an attacker with control of `--commit-hash` to execute arbitrary commands on the system running Wrangler. The vulnerability is generally hard to exploit, but primarily affects CI/CD environments where the parameter is populated from external, potentially untrusted sources.
Risk Assessment
In CI/CD environments, an attacker can execute arbitrary commands on the system, potentially leading to compromise of build and deployment processes and infrastructure takeover.
Recommendation
Update Wrangler to a patched version and avoid passing untrusted values to the `--commit-hash` parameter.

SummaryA command injection vulnerability (CWE-78) has been found to exist in the `wrangler pages deploy` command. The issue occurs because the `--commit-hash` parameter is passed directly to a shell command without proper validation or sanitization, allowing an attacker with control of `--commit-hash` to execute arbitrary commands on the system running Wrangler. Root causeThe commitHash variable, derived from user input via the --commit-hash CLI argument, is interpolated directly into a shell command using template literals (e.g., execSync(`git show -s --format=%B ${commitHash}`)). Shell metacharacters are interpreted by the shell, enabling command execution. ImpactThis vulnerability is generally hard to exploit, as it requires --commit-hash to be attacker controlled. The vulnerability primarily affects CI/CD environments where `wrangler pages deploy` is used in automated pipelines and the --commit-hash parameter is populated from external, potentially untrusted sources.
