CVSS v3.1 |
| 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. |
| User-controlled header names and values containing newlines can allow injecting HTTP headers. |
| When using http.cookies.Morsel, user-controlled cookie values and parameters can allow injecting HTTP headers into messages. Patch rejects all control characters within cookie names, values, and parameters. |
| The poplib module, when passed a user-controlled command, can have
additional commands injected using newlines. Mitigation rejects commands
containing control characters. |
| The imaplib module, when passed a user-controlled command, can have additional commands injected using newlines. Mitigation rejects commands containing control characters. |
| User-controlled data URLs parsed by urllib.request.DataHandler allow injecting headers through newlines in the data URL mediatype. |
| When folding a long comment in an email header containing exclusively unfoldable characters, the parenthesis would not be preserved. This could be used for injecting headers into email messages where addresses are user-controlled and not sanitized. |
