Path traversal vulnerabilities occur when an application fails to properly sanitize user-supplied input containing directory traversal sequences, such as dot-dot-slash patterns. In the context of the migration revision command analyzed here, the flaw stems from the insecure handling of the migration name parameter supplied directly via the command-line argument -m. When a user or an automated CI/CD pipeline passes a crafted migration name containing traversal sequences, the application fails to confine the resulting file creation operation to the designated migrations directory. As a result, the input escapes the intended directory boundaries. Under specific execution conditions, this allows an attacker with input-influencing privileges to force the underlying tool to create a `.sql` file in an arbitrary location on the filesystem that is writable by the executing user process. This vector is particularly dangerous when integrated into automated workflows, web hooks, or insecure CI/CD pipelines where untrusted external data can be injected into the revision arguments. Without strict validation, sanitization, and path canonicalization routines, the software blindly trusts the provided string, leading to unauthorized file creation and potential system compromise or configuration tampering.
DailyCVE Form:
Platform: Migration Tool
Version: 1.0.3
Vulnerability: Path Traversal
Severity: Medium
date: October 16 2026
Prediction: Already Patched
What Undercode Say:
Executing revision command with traversal payload migration-tool revision -m "../../../tmp/malicious_migration" Verifying arbitrary file creation ls -la /tmp/malicious_migration.sql
Exploit: (Educational Purposes!)
Crafting input to escape migrations directory via -m argument ./migration-tool revision -m "../../app/config/malicious"
Protection:
Upgrade the tool to version 1.0.3 or later immediately. Ensure that input validation and path canonicalization are enforced on all migration names. Avoid passing untrusted input or external parameters directly into automation scripts invoking the revision command.
Impact:
An attacker capable of influencing the migration name via insecure automation or CI/CD pipelines can cause the tool to write arbitrary `.sql` files to any location writable by the executing user, potentially leading to unauthorized file manipulation or system compromise.
