Vulnerability Details

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. An attacker could exploit this to:

• Run any shell command.
• Exfiltrate environment variables.
• Compromise the CI runner to install backdoors or modify build artifacts.

  Mitigation
• Wrangler v4 users are requested to upgrade to Wrangler v4.59.1 or higher.
• Wrangler v3 users are requested to upgrade to Wrangler v3.114.17 or higher.
• Users on Wrangler v2 (EOL) should upgrade to a supported major version.

Found in base branch: main

Vulnerability Details

Undici is an HTTP/1.1 client for Node.js. Prior to 7.18.0 and 6.23.0, the number of links in the decompression chain is unbounded and the default maxHeaderSize allows a malicious server to insert thousands compression steps leading to high CPU usage and excessive memory allocation. This vulnerability is fixed in 7.18.0 and 6.23.0.
